If your teeth have a worn appearance, it's possible you have a habit you're not even aware of: clenching or grinding your teeth. Also called “bruxism,” this destructive action causes your top and bottom teeth to come together or scrape past each other with a force that's many times what is normal for biting and chewing.
So what's normal? This can be expressed in terms of pounds. An adult usually exerts a force of 13-23 pounds to bite or chew food. But we have the potential to generate as much as 230 pounds of force, or 10 times what's normal. A “parafunctional” force of this magnitude applied repeatedly is bound to stress your teeth and other areas of your oral system. Besides wearing away the enamel of your teeth — and maybe even some of the softer dentin layer underneath — you may experience muscle spasms or pain in your jaw joints. Serious cases of wear can lead to “bite collapse” in which your face actually changes shape as your cheeks and lips lose support. This can make you look prematurely aged.
What can be done? To prevent further wear, we can fabricate for you a thin, plastic mouthguard that will protect your teeth at night or during times of intense stress. We can also recommend ways to temporarily relieve the discomfort that your grinding/clenching habits can cause. Heat and/or anti-inflammatory medication, for example, can be helpful.
If your tooth wear is minor (raggedness along the biting edge of a tooth or teeth) you may not need any restorative work. However, if tooth wear has already caused changes to your teeth and bite that you find aesthetically or functionally unacceptable, we can restore lost tooth structure in a variety of ways. Veneers and crowns are two examples.
If you have any questions about tooth wear or grinding habits, please contact us today to schedule an appointment for a consultation. You can learn more about this topic by reading the Dear Doctor magazine article “How And Why Teeth Wear.”
In modern society, a bright, white smile conveys optimal health, youth and sound teeth. However, various influences including age, wear, diet, and lifestyle may prevent you from having and maintaining the glistening smile you long to share with the world. Luckily, there are many safe, inexpensive, and successful treatment options for discolored or stained teeth.
We can perform a “power bleaching” in our office to whiten teeth that are severely stained or discolored. This procedure whitens the external surfaces of the teeth by using a high concentration (35-45%) hydrogen peroxide solution, which is sometimes activated by a specialized light. To prevent irritation of the mouth's soft tissue lining during this procedure, we will isolate your gums and membranes with a rubber dam, a silicone or other effective barrier. Professionally applied in-office power bleaching provides control, speed, and predictability capable of lightening teeth up to ten shades in an hour. Don't try this at home! Our staff will take precautions in the office to avoid side effects and possible tooth sensitivity.
We can also provide you with custom-made, vacuum-formed, plastic bleaching trays for use with a take-home whitening application. In this instance, a gel made from carbamide peroxide (4-7% hydrogen peroxide, safe for home use) is delivered to the tooth surfaces in the bleaching trays. You will need to wear the tray for 30 minutes twice a day, which is a longer process than in-office bleaching. The first subjective signs of whitening will occur after three or four sessions, allowing whitening of up to eight shade units.
Another home-based option, whitening strips, essentially look like band-aids for the teeth. They are capable of lightening teeth by about three shades after being worn directly on the surface of the teeth for 30 minutes twice a day for one week.
If you have always wanted whiter teeth, schedule an appointment so we can determine which of these treatment options would work best for you. For more information on the fundamentals of teeth whitening, read the informative Dear Doctor magazine article “Teeth Whitening: Brighter, Lighter, Whiter...”
Tooth decay is not trivial. It's a worldwide epidemic, one of the most common of all diseases — second only to the common cold. It affects more than one fourth of U.S. children of ages 2 to 5 and half of those 12 to 15. Among adults, tooth decay affects more than ninety percent of those over age 40.
Prevention of cavities starts with a healthy diet and effective brushing and flossing, but it is much more complex than that. Three strategies for reducing dental caries (tooth decay) include:
Protect with Fluoride and Sealants
This works best when fluoride is applied to the crystalline coating of your child's teeth just after they push through the gums (erupt). The fluoride becomes incorporated into the tooth's surface and acts as a barrier to decay. Studies have shown that low doses of fluoride are safe and effective.
Dental sealants are used as a companion to fluoride because they seal tiny pits and fissures in the tooth's structure, creating an even stronger barrier.
Modify Oral Bacteria
Every mouth contains bacteria, no matter how well you clean your teeth. Not all bacteria cause tooth decay. The problem bacteria are those that produce acid as a byproduct of their life processes. We can identify acid-producing bacteria in your mouth, you can reduce their concentrations using antibacterial mouthrinses such as chlorhexidine, and pH neutralizing agents (substances that reduce the amount of acid).
Reduce Sugars in Your Diet
Bacteria in your mouth ferment sugars and other carbohydrates, producing acids that eat into the mineralized outside structure of your teeth, the enamel. So eating fewer sugars — particularly added sugars such as those in juices, sodas, candy and other sweets — will help prevent decay. Your total sugar intake should be less than fifty grams, or about ten teaspoons, per day. If you begin to read labels showing sugar content of common foods, you may be surprised at the amount you consume without knowing it.
If you must snack between meals, non-sugary snacks like raw vegetables and fresh fruits create a better environment for your teeth.
Xylitol, an “alcohol sugar” used in some chewing gums and dental products, has been shown to reduce decay-producing bacteria.
Try these easy strategies to keep your teeth healthy and functional throughout your lifetime.
When it comes to sensitive gums during pregnancy, Nancy O'Dell, the former co-anchor of Access Hollywood and new co-anchor of Entertainment Tonight, can speak from her own experience. In an interview with Dear Doctor magazine, she described the gum sensitivity she developed when pregnant with her daughter, Ashby. She said her dentist diagnosed her with pregnancy gingivitis, a condition that occurs during pregnancy and is the result of hormonal changes that increases blood flow to the gums. And based on her own experiences, Nancy shares this advice with mothers-to-be: use a softer bristled toothbrush, a gentle flossing and brushing technique and mild salt water rinses.
Before we continue we must share one important fact: our goal here is not to scare mothers-to-be, but rather to educate them on some of the common, real-world conditions that can occur during pregnancy. This is why we urge all mothers-to-be to contact us to schedule an appointment for a thorough examination as soon as they know they are pregnant to determine if any special dental care is necessary.
Periodontal (gum) disease can impact anyone; however, during pregnancy the tiny blood vessels of the gum tissues can become dilated (widened) in response to the elevated hormone levels of which progesterone is one example. This, in turn, causes the gum tissues to become more susceptible to the effects of plaque bacteria and their toxins. The warning signs of periodontal disease and pregnancy gingivitis include: swelling, redness, bleeding and sensitivity of the gum tissues. It is quite common during the second to eighth months of pregnancy.
Early gum disease, if left untreated, can progress to destructive periodontitis, which causes inflammation and infection of the supporting structures of the teeth. This can result in the eventual loss of teeth — again, if left untreated. Furthermore, there have been a variety of studies that show a positive link between preterm delivery and the presence of gum disease. There has also been a link between an increased rate of pre-eclampsia (high blood pressure during pregnancy) and periodontal disease. Researchers feel this suggests that periodontal disease may cause stress to the blood vessels of the mother, placenta and fetus.
