Supernumerary Teeth Explained!

MOST PEOPLE WILL develop a total of twenty baby teeth that are gradually replaced by a total of thirty-two adult teeth. Sometimes those teeth don’t all appear, a condition called hypodontia. In even rarer cases, all the normal teeth will be present, plus at least one extra! These extra teeth are supernumerary teeth, and the condition is called hyperdontia.

Why Do Extra Teeth Form?

There are two main competing theories about what causes supernumerary teeth. One possibility is that an individual tooth bud might divide abnormally and result in two teeth instead of one. Another is that extra teeth could result from hyperactivity in the dental lamina (the tissue in our jaws that forms tooth buds). Heredity might also play a role.

Supernumerary teeth can come in various forms. They might be conical (peg-shaped), tuberculate (with multiple cusps), supplemental (duplicates of normal teeth), or odontoma (a mass of dental tissue that doesn’t quite form a tooth).

Who’s Most Likely To Have Them?

Hyperdontia affects far more men than it does women. One study done in southern China showed that only 2.7 percent of children had supernumerary teeth, with a ratio of 6.5 affected boys for every 1 affected girl. They’re also more common in permanent teeth than baby teeth. Several developmental conditions increase the likelihood of having at least one extra tooth, such as cleft lip or palate and Gardner syndrome, but there’s still a lot of debate about what actually causes hyperdontia.

How Do These Teeth Affect Oral Health?

The most obvious effect of a supernumerary tooth is on the appearance of the person’s smile, but not all of the concerns are cosmetic. They often remain impacted in the gum line and can cause crowding and alignment problems for the normal series of teeth, sometimes making it harder for them to erupt. In serious cases, they can cause root resorption in the surrounding teeth.

Treatment For Hyperdontia

Sometimes, an extra tooth won’t cause any problems for the rest of the teeth, in which case it can remain where it is. If it is causing problems, however, the typical treatment is simply to extract the extra tooth or teeth so that the normal teeth will have enough room.

Getting Wise About Wisdom Teeth

WISDOM TEETH REMOVAL is a major rite of passage for many in their late teens and early twenties. They post images of their swollen cheeks on social media, share videos of themselves acting loopy from the anesthetics on YouTube, and enjoy an excuse to drink as many smoothies as possible. But why do we have these teeth in the first place if most of us just get them removed?

Vestigial Third Molars

The prevailing theory about why we have a third set of molars is that our ancient ancestors needed them to effectively grind up the foods they ate. Unlike a modern diet of softer cooked and processed foods, theirs consisted of roots, fibrous plants, and raw meat, so they actually needed their wisdom teeth.

Some theorize that it is our diets more than our genes that determine whether or not we have room in our jaws for all thirty-two teeth. Eating a prehistoric diet during the developmental years might stimulate enough growth to accommodate them, while a modern diet does not (but we don’t recommend testing this theory).

Why Wisdom Teeth Are Removed

A small (but growing) percentage of people never get wisdom teeth at all, or have fewer than four, but for most, they show up between ages 17 and 21. With enough room, they can come in with no trouble, but many people experience problems that necessitate extraction.

The main reasons for wisdom tooth extraction are impaction(meaning they are trapped beneath the gums, where they can form cysts and damage nearby teeth and bone) and insufficient room in the jaw, which causes damage, crowding, and pain. Some dental work may require wisdom teeth removal as well. If your wisdom teeth come in correctly and you are able to clean them properly, you might not need to have them removed, so enjoy your extra chewing power!

Tips To Remember Before You Get Yours Removed

If your wisdom teeth do need to be removed, be sure to rest up before the big day so that you’ll be able to heal as quickly as possible. Afterward, stay well hydrated and avoid alcoholic, caffeinated, carbonated and hot beverages for the first day or two, because these can all cause problems with the extraction sites. However, you can enjoy as many soft foods like ice cream, yogurt, and applesauce as you want! After a couple of days, you can add in soups, but wait a week or two before you go back to hard or chewy foods.

No two cases of wisdom teeth removal are exactly the same, which is why we approach them on a case-by-case basis. We watch their progress as they come in to determine whether extraction will be necessary.
