Dental Questions: Is Nitrous Oxide Safe?

Nitrous oxide, also known as "laughing gas," is the most common form of sedation used at dental offices nation wide. It can calm anxious patients and turn a stress filled dental visit into a relaxed experience. With its strong effects, you may be concerned that nitrous oxide has the potential to be harmful when used at dental visits. On the contrary, it is one of the safest relaxation drugs at a dentist's disposal. Take a look!

When administered at a dental office, pure nitrous oxide is mixed with pure oxygen in a mixture not exceeding one-to-one. In this setup, there is actually more oxygen in the nitrous mask than in ambient air, making it safe for those with breathing problems such as asthma. The nitrous system delivers the gas via a nose hood that both provides medicine to the patient and removes it as they exhale. This prevents other occupants in the room from receiving secondary doses of nitrous. It typically takes about five to ten minutes for a patient to feel the effects, and about the same amount of time for the gas to wear off when stopped. Most patients are fine to drive themselves home or return to work after receiving nitrous oxide sedation. 

Nitrous oxide works by stimulating receptors in the brain stem to create a calm, sedated and relaxed sensation in the recipient. Contrary to the name "laughing gas," it should make you feel sleepy or compliant during treatment. When used properly (in a healthcare setting with proper equipment) it is virtually impossible to overdose on nitrous. The gas is eliminated from your body by breathing, where you gradually exhale it from your blood supply and back into the nitrous mask. 

Naturally, nitrous oxide isn't for everyone and should only be used for patients that truly need sedation. Needlessly adding nitrous to a dental procedure adds unnecessary risks and difficulties to the treatment.

Dental Questions: Do whitening strips work?

Tooth whitening is the most commonly requested cosmetic procedure at dental offices nation wide. Lightening the shade of dental enamel can create a dramatic change that draws attention to your smile. As such, you have probably seen products like Crest WhiteStrips at your local pharmacy and wondered if they were worth the investment. Why would someone choose these over a professional bleaching treatment performed at a dental office? For these answers and more, read on!

Any tooth whitening product that works (from a scientific perspective) will have some concentration of a peroxide compound. Peroxide works by oxidizing the pigments that have leached into your teeth and removing their colors. Typically, dental products contain either carbamide peroxide or hydrogen peroxide suspended in some type of gel. 

The main difference between a whitening strip, a bleach tray and an in-office bleaching session is the concentration of peroxide. Since these compounds are slightly caustic, high levels of peroxide can cause gum irritation or discoloration. For an in-office whitening session, the gums can be safely guarded and isolated, allowing us to use a higher level of peroxide. As a result, you will see an almost instantaneous change in the shade of your dental enamel. With a product like WhiteStrips, the plastic tray is not custom molded to your teeth and is bound to contact your gums or become leaky out the sides. Hence, a lower concentration of peroxide must be used, with noticeable results taking longer to appear. 

Which type of whitening is best? That can only be answered on a patient-by-patient basis. For those looking for a cost effective change without a deadline, over-the-counter whitening strips are a great option. If you're looking for a single treatment that brings almost instant results, in-office bleaching might be better. It really depends on what you hope to accomplish and how much time you can devote to your treatment.

Dental Questions: How can I clean around braces?

Braces can make cleaning any mouth very difficult. The wires, bulky brackets and food trapping ledges all contribute to problems with home care. Fortunately, there are many great products and techniques for keeping your orthodontic appliances clean. Take a look!

A typical example of floss threaders.

One of the most obvious difficulties in cleaning around braces is the inability to floss between teeth. The orthodontic wire prevents regular dental floss from reaching the critical areas at/beneath the gum line. A typical solution to this problem is using a floss threader or dental floss with a built in threader tip. These products allow you to push the floss underneath the wire and reach all areas of the teeth. Newer devices like GumChucks ORTHOgami achieve the same outcome, but with a different form factor. For younger patients, dental picks and floss brushes should be used carefully, as they have the potential to damage the gum tissue and cause bleeding. They are, however, useful for cleaning sticky food out from between the wire and tooth. 

GumChucks ORTHOgami

Brushing around the wires and brackets relies more on careful technique than a special product. You will probably need to make a conscious effort to get the toothbrush positioned underneath the wire and into the various angels of the brackets. Some companies sell special orthodontic brushes with smaller heads for manuvering around the appliances. Still, a standard toothbrush and good technique should be sufficient for most patients. Keeping the gums and tooth surfaces around the brackets healthy is a priority for any patient in braces. You don't want to finish your orthodontic treatment only to have cavities in your beautiful smile!

At Thousand Oaks Family Dentistry, we know that braces can turn dental hygiene into even more of a chore. We are here to make the process as easy as possible. If you would like to know more about braces, orthodontics, toothbrushes or dental cleanings, please give our office a call!

Dental Questions: Is coffee bad for your teeth?

Coffee: possibly the most widely consumed non-alcoholic beverage other than water. With about 400 million cups drank EACH DAY, it is difficult to deny it's importance in our daily routines. As you probably know (or experienced), the dark pigments in this drink can cause discoloration or yellowing of the dental enamel. Beyond the cosmetic concerns, can coffee consumption harm your teeth? While it is difficult to give a definitive yes or no, there are some considerations you should take when going back for your next cup of joe. 

As a reminder, anything you eat or drink other than water has the potential to demineralize enamel and start the tooth decay process. Black coffee has a pH of about 5, meaning it is acidic enough to weaken enamel and cause initial decalcification. However, coffee has no carbs or sugars and thus cannot fuel the cavity-causing bacteria. The problem arises when sugar, cream, milk or other products are added to your beverage. Even something non-sweet like skim milk has the carbs necessary to feed bacterial growth and cause new decay.

Are we suggesting you quit drinking coffee cold turkey? Of course not! Still, there are ways you can adjust your consumption to better protect your teeth. Keep in mind that its not the amount, but the duration of carbohydrate consumption that determines tooth decay. Try to limit your coffee drinking sessions to set time frames, rather than sipping on one or two cups all morning. Swishing with water after drinking can help too, and protects against further staining!

At Thousand Oaks Family Dentistry, we know that creating good dietary habits is a moving target. We are always here to help you make great choices in protecting and improving the health of your teeth. If you would like to know more about tooth decay, how to protect your teeth or any other dental topics, please give our office a call!

Dental Questions: Does every tooth extraction require stitches?

Wether you've had a tooth extracted before or not, chances are that you have some idea of what is involved in this procedure. You would probably expect that every patient gets stitches (professionally called sutures) before they are allowed to leave. A dentist wouldn't let you go with a giant hole in your jaw, right? On the contrary, there are many times that sutures aren't a necessary step after extracting a tooth and do not improve the healing process. Take a look!

In the mouth, sutures can assist in the healing of gums and other soft tissues by holding them in a desired place. In complex dental extractions, such as removing wisdom teeth or impacted teeth, the bone and gums around the tooth may need to be moved or partially removed. To ensure that the gums heal cleanly around the jaws and do not create a food trap, sutures are used to approximate natural soft tissue contours. Additionally, stitches are used to help in the formation of healthy blood clots and to help keep grafts and membranes in place during critical healing periods. 

For "simple" dental extractions, sutures are not always required. When there is minimal manipulation of the gums and bones AND the patient has a healthy immune system, it is reasonable to expect that the tooth site will heal with no sutures. For most patients, a "scab" will begin to form in the mouth before they leave the dental office, and nearly all bleeding will cease within 2 hours. Research shows that sutures will not help the gums or bones heal faster or assist in preventing post extraction infection. On the contrary, the most important determining factor in extraction outcomes is following the post operative instructions given to you by your dentist!

It is often hard to tell if a patient will need sutures until after the extraction procedure is finished. Sometimes, even the most simple-seeming teeth require more manipulation and work than they initially let on. As with every procedure, we do our best to inform you of changes to your treatment plan as they arise. If you would like to know more about tooth extractions, oral surgery or other dental procedures, please give our office a call!

Dental Questions: Why would a dentist place a temporary filling?

A filling is a filling, right? Then why would a dentist send you home with a "temporary" filling? What makes it any different from the permanent fillings you have on your other teeth? Do you need to worry about it falling out? Read on to see how and why dentists use temporary fillings to save and protect teeth!

A temporary or sedative filling is a type of dental procedure performed on a tooth with an uncertain prognosis or as an intermediate measure before further treatment. Imagine a patient who comes in for an emergency appointment with a large, painful cavity. While definitively saving the tooth may require a few different lengthy treatments, a dentist can remove decay and provide a temporary filling that same visit. This allows a tooth to be stabilized and desensitized so the patient can continue to function until a more definitive plan can be made. Many times, it is simply too early to determine the status of the tooth's nerves or gums and thus a temporary filling acts as a good interim measure. 

The most common material used in temporary fillings is a tooth colored compound called glass ionomer. This product bonds to tooth enamel, reacts well with moisture and has a natural calming effect on aggravated tooth nerves. Additionally, it enhances the effects of fluoride to provide extra defense against decay. The trade off is that glass ionomer is much weaker than permanent filling materials and does not stand up against tooth brushing, eating or chewing over time. Still, it's properties make it an ideal material to be used in temporary situations. 

How long will your temporary filling last? That question is impossible to answer without knowing the condition of the remaining tooth. In general, you should always end your temporary filling appointment with a plan for a permanent solution in the future.

Dental Questions: Why do my teeth shred floss?

Shredding or tearing floss is a common (and annoying) obstacle to keeping your teeth clean. Having to constantly switch to a new piece or use a frayed length of floss gets old fast. What could be causing your flossing woes? Take a look!

Between every two adjacent teeth exists a contact where they touch each other at their widest points. This space should be smooth and flowing, without any ridges or sharp corners. If you are shredding floss, there must be some sort of edge in this area that is disrupting the floss fibers. Many times, this is the result of a filling placed between two teeth that needs to be smoothed out. Small pieces of excess filling material, called flash can become dislodged and create an edge that tears at the floss fibers. The solution to this problem is to have a dentist smooth out or (in more drastic situations) replace the filling, creating a more anatomically correct shape. 

Floss can also shred due to food, tartar, or other debris lodged in between teeth. Tartar, in particular, is rough and irregular, creating a surface that easily tears at floss fibers. The solution to this problem is to have a dentist clean the affected teeth, and return for normal dental hygiene appointments. When combined with regular cleanings, good flossing technique will remove stuck food and prevent the formation of harmful tartar in the future. 

Flossing every day is one of the easiest and most beneficial additions to your home hygiene routine. Even if your teeth shred floss, we urge you to continue to use it daily to help maintain the health of your gums and bones. If you would like to know more about flossing, brushing, oral health or any other dental topics, please give our office a call!

Dental Questions: Why are x-rays so useful?

In modern dentistry, we take x-rays fairly frequently. The average patient will receive four "periodic" radiographs annually, and an entire "full mouth" set of images every five to seven years (depending on multiple factors). Why do we need so many pictures? As it turns out, x-rays are an invaluable tool in diagnosing, documenting and monitoring changes in dental diseases. Take a look!

Dental x-rays give a dentist much more information that simply "looking in the mouth." In regards to tooth decay, radiographs can show cavities forming in areas that are impossible to visualize, such as in-between two teeth. Furthermore, they give more information on the location and depth of decay, helping inform decisions on placing fillings versus crowns, the risk of nerve irritation and what materials to use to fill the tooth. In most instances, we will not perform a filling on a tooth without an acceptable x-ray of the effected area. Radiographs are also necessary in assessing gum disease and bone loss. They can document the amount and pattern of recession, helping make decisions on dental cleanings and possible periodontal surgeries. In severe circumstances, heavy tartar hidden beneath the gum line will be visible on radiographs as well.

X-rays are also of great use in documenting and monitoring dental problems. Particularly in working with insurance companies, radiographs help demonstrate the necessity of certain procedures. This can improve the approval process and speed up reimbursements. Additionally, x-rays can help track the changes in dental conditions over time, aiding in decisions on treatment or continued monitoring. 

This image shows the progression of gum disease, as seen on an x-ray. The small white bumps that form on the sides of the teeth are tartar below the gumline. 

Radiographs are useful in visualizing much more than gum disease and tooth decay. Procedures like root canals, extractions and implants are impossible to perform without good radiographs. To learn more about the diagnostic tools we use in dentistry, please give our office a call. 

Dental Questions: Is tooth decay related to genetics?

We often hear of people born with "soft enamel" or "weak teeth" that have left them with a lifetime of dental problems. Naturally, genetics has to play some role in tooth decay- right? How else can we explain the the stark differences in dental experience across the population? While the foundations of dental disease are hereditary, the full answer might surprise you!

For starters, genetics can play a role in cavities and tooth decay. However, these problems affect a very small group- less than 1% of the general population. Hereditary conditions like amelogenesis imperfecta, dentinogenesis imperfecta and dentin dysplasia all cause less resistance to tooth decay and increased dental needs over a lifetime. They also come with very obvious cosmetic changes, like mottled coloring, brown/ blue enamel tones or notched edges. If your teeth appear "normal," chances are you aren't affected by one of these conditions. In addition, there are some developmental issues that can lead to weaker enamel as well. Notably, incisor-molar hypoplasia appears with mottled enamel on the permanent incisors and first molars that is less resistant to tooth decay. 

In reality, the inherited component of tooth decay comes from bacterial genetics. In many instances, the cavity experience of a child's mother will predict the next generation's rate of decay. As the typical primary caregiver, close contact between mother and child leads to bacterial inoculation during a developmental period that defines the child's future oral bacteria. This is one of the reasons we stress not sharing utensils or cleaning pacifiers with spit. While all children will eventually become inoculated, delaying the start time can lower the tooth decay experience. Additionally, learned habits can play a large shaping role in tooth decay. Attitudes towards snaking, brushing/flossing, sugary foods and dental treatment become learned at a young age and can be hard to correct.  

The important message here is that very few patients actually have "soft enamel," and improving dental health is an attainable goal. Controlling sugar intake, daily brushing/ flossing and frequent hydration with fluoridated water are easy and scientifically proven to lower the risk of developing cavities.

Dental Questions: Why do I have to wait for my implant crown?

If you have had an implant placed at our office or one of our specialists' offices, chances are you had to wait three to four months for the implant to heal before having a crown placed on it. Conversely, you may know someone who had an implant placed and left the same day with a (temporary) Crown. Why did you have to wait all that time for your crown? The reality is that there are hundreds of approaches to implant placement, and our office uses the most predictable and conservative method possible. 

Dental implants gain their rigidity in the mouth from two primary sources: the physical retention of the implant screw in bone and the growth of new bone around the implant. The screw force that develops immediately as the implant is placed is formally known as primary stability. This type of retention locks the implant and allows the new bone to form around the it, creating a phenomenon known as osseointegration or secondary stability. Osseointegration creates the definitive force that stabilizes the implant crown for daily use. 

Some techniques will rely on primary stability to support a crown on the implant immediately. In these methods, the screw force of the implant is absorbing all the forces of biting or chewing. Any movement or looseness would prevent new bone growth and could lead to implant failure. At Thousand Oaks Family Dentistry, we know a dental implant is a big investment into your future comfort and quality of life. We prefer to use the most predictable implant techniques and wait for secondary stability to develop. Waiting three to four months for your implant to fully heal is a small price to pay for better chances at success!

We know that choosing a treatment to replace a missing tooth can be overwhelming. At our office, we pride ourselves in offering patients all their treatment options, along with a thorough evaluation to help you pick the right choice.
