Contrary to what you might think, a knocked out tooth doesn’t inevitably mean tooth loss. Time is of the essence — the shorter the interval between injury and replanting the tooth, the better the tooth’s long-term survival. The longer the interval, on the other hand, the less likely the tooth can survive beyond a few years. That phenomenon is due to the mouth’s natural mechanism for holding teeth in place.
The tooth root maintains its attachment with the jaw bone through an intermediary tissue known as the periodontal ligament. Tiny fibers from one side of the ligament securely attach to the tooth root, while similar fibers attach to the bone on the opposite side of the ligament. This maintains stability between the teeth and bone while still allowing incremental tooth movement in response to mouth changes like tooth wear.
While the ligament fibers will attempt to reattach to a replanted tooth’s root, the longer the tooth is out of the socket the less likely the fibers will fully reattach. An “ankylosis” may instead form, in which the root attaches directly to the jaw bone without the periodontal ligament. In this situation the body no longer “recognizes” the tooth and begins to treat it like a foreign substance. In all but the rarest cases, the tooth root will begin to resorb (dissolve); at some point (which varies from patient to patient) the attachment becomes too weak for the tooth to remain in place and is lost.
Ideally, a knocked out tooth should be replanted within 5 minutes of the injury (for step-by-step instructions, refer to The Field-Side Guide to Dental Injuries available on-line at www.deardoctor.com/dental-injuries). Even if you pass the 5-minute window, however, it’s still advisable to attempt replanting. With a subsequent root canal treatment (to remove dead tissue from the inner tooth pulp and seal it from infection), it’s possible the tooth can survive for at least a few years, plenty of time to plan for a dental implant or similar tooth replacement.

It can start with a simple twinge or be as severe as excruciating pain. From time to time, we have patients asking questions about tooth sensitivity — what causes it? What can be done about it? For these reasons, we have put together the following list of frequently asked questions (FAQs) so that you can develop a healthy understanding about this painful and often avoidable condition.
What is tooth sensitivity?
The first layer of protection of the teeth is enamel. Enamel is a dense crystalline structure, the hardest substance produced by animals. It is an inert substance that has no nerve supply and thus it protects the teeth from temperature and pressure changes. When it is compromised, worn thin, or exposed due to gum recession, it leaves the dentin exposed and vulnerable. Unlike enamel, dentin is living and has delicate nerve fibers within it.
What triggers tooth sensitivity?
Once dentin is exposed, it can become sensitive. It typically occurs when the dentin comes in contact with heat, cold, or the “double whammy” combination of both cold and sweets. Even the bristles of a soft toothbrush can irritate exposed dentin causing sensitivity and pain.
What can be done to minimize tooth sensitivity?
One of the simplest ways to minimize or prevent sensitivity is by teaching proper brushing techniques so that teeth are cleaned without causing either sensitivity or damage. Brushing too hard is a frequent culprit. Being overzealous can literally cause gum recession, leave dentin, and wear it away leaving it grooved. Another step to minimize sensitivity is to use a toothpaste containing fluoride. Fluoride increases the strength of tooth surfaces and thus makes teeth more resistant to attack by acids and sweets. If severe, we may need to apply a barrier to cover the sensitive areas. These barriers may range from concentrated fluoride varnishes to replacing lost tooth structure with filling materials.

Junk food and between-meal sweets are a habit for many of us, even though we know it is bad for our bodies and our teeth. As adults, we are responsible for our own choices. As parents, we are also responsible for our children's choices, and for teaching them to choose wisely.
Celebrity Chef Cat Cora offers the following six suggestions for leading children to a healthy lifestyle. Cora is a star of Iron Chef America and author of Cat Cora's Classics with a Twist: Fresh Takes on Favorite Dishes, in which she reveals healthier versions of classic recipes. In her remakes she shows how to cook with a lot of flavor while reducing fat and sugar. Cora has four young sons, so her methods are not just theories — they have been practiced in real life.
1. Remember who's the boss.
“My kids have never had fast food,” Cora said in a recent interview with Dear Doctor magazine. “The parents have a choice to do that or not,” she said. “The kids are not going to the grocery store to shop; the kids are not driving themselves through fast food chains.”
2. Make your rules clear and stick to them.
“Right now my 7-year-old tries to be picky, but it's really about us being consistent as parents,” Cat said. For example, in her household pizza is served only at the weekly pizza and movie night. The kids get a healthier version of what they want, so they don't feel deprived. The evening includes air-popped popcorn without butter — and no soda, which is bad for teeth because of its sugar and other chemical ingredients.
3. Offer your children a variety of foods and tastes.
Cora made sure her children tried different foods and spices from infancy, so they are open to trying new things. It's easier to get all the nutrition you need if you eat a wide variety of foods.
4. Learn to make tasty substitutions for sugar.
When her children were babies, Cora stopped relying on bottles and sippy cups as soon as possible, reducing her children's likelihood of developing tooth decay due to sugary residues remaining in their mouths. Now that they are older, she uses tasty substitutes for sugar such as fruit purees and the natural sugar substitute Stevia.
5. Include the children in meal planning.
Kids are more likely to eat a meal they are involved in planning and cooking. For example, ask them which vegetable they would like to have (not whether they want to have a vegetable).
6. Model healthy behavior for your kids.
Parents are the best role models. This is true not only for food choices, but also for exercise and maintaining a healthy lifestyle.
While tooth decay and periodontal (gum) disease destroy more teeth than any other causes, both of these diseases are largely preventable with proper oral hygiene and dental treatment. It’s more than possible, then, to enjoy a lifetime of healthy, disease-free teeth.
But even with healthy teeth, the effects of aging will cause tooth wear over time. And although we can’t prevent the aging process from occurring altogether, there are steps we can take not to accelerate the process.
Most tissues, including bone and teeth, have a growth cycle in which older cells are broken down (known as catabolism), removed and replaced by newer cells (anabolism). As we develop during childhood, the growth phase exceeds breakdown; when we reach adulthood, the two phases come into equilibrium. But as we age, breakdown will gradually overtake growth. This aging effect results in, among other outcomes, tooth wear.
“Normal” wear appears to be greatest — and most visible — along the biting surfaces of the teeth. The forces generated when we bite or chew causes enamel to erode over time. Unfortunately, you can accelerate this process through bad oral habits: clenching or grinding teeth, often times at night while you sleep, as well as habitually chewing on hard objects like nails or pencils.
Normal forces generated when we bite or chew are actually beneficial for dental health — they help stimulate bone growth. But when they exceed their normal range as when we clench or grind our teeth, they can increase tooth wear and cause other problems such as diminished function or changes in appearance, such as a shortened facial height.
To slow the rate of wear, it’s important to modify any behaviors that may be contributing to it. In many cases an occlusal night guard worn while you sleep helps prevent teeth clenching. You may also need assistance with stress management, a major trigger for these kinds of habits, through biofeedback therapy or counseling.
If you’ve already encountered excessive wear, bonding techniques using colored composite resin, veneers or crowns that attach directly to the teeth can restore lost function and rejuvenate the appearance and color of your teeth. We can perform a “smile analysis” to determine if one of these techniques is right for you to help you regain a more youthful and attractive smile.

Periodontal (gum) disease is mainly caused by bacterial plaque built up on tooth surfaces due to ineffective oral hygiene. For most cases, treatment that includes plaque and calculus (tartar or calcified plaque) removal and renewed daily hygiene is highly effective in stopping the disease and restoring health to affected gum tissues.
However, you might have additional health factors that may make it more difficult to bring the disease under control. If your case is extreme, even the most in-depth treatment may only buy time before some or all of your teeth are eventually lost.
Genetics. Because of your genetic makeup, you could have a low resistance to gum disease and are more susceptible to it than other people. Additionally, if you have thin gum tissues, also an inherited trait, you could be more prone to receding gums as a result of gum disease.
Certain bacteria. Our mouths are home to millions of bacteria derived from hundreds of strains, of which only a few are responsible for gum disease. It’s possible your body’s immune system may find it difficult to control a particular disease-causing strain, regardless of your diligence in oral care.
Stress. Chronic stress, brought on by difficult life situations or experiences, can have a harmful effect on your body’s immune system and cause you to be more susceptible to gum disease. Studies have shown that as stress levels increase the breakdown of gum tissues (along with their detachment from teeth) may also increase.
Disease advancement. Gum disease can be an aggressive infection that can gain a foothold well before diagnosis. It’s possible, then, that by the time we begin intervention the disease has already caused a great deal of damage. While we may be able to repair much of it, it’s possible some teeth may not be salvageable.
While you can’t change genetic makeup or bacterial sensitivity, you can slow the disease progression and extend the life of your teeth with consistent daily hygiene, regular cleanings and checkups, and watching for bleeding, swollen gums and other signs of disease. Although these additional risk factors may make it difficult to save your teeth in the long-run, you may be able to gain enough time to prepare emotionally and financially for dental implants or a similar restoration.
