Baby (primary) teeth look and function much like their permanent counterparts. Besides having a visible crown, they also have roots that maintain contact with the jawbone.
But there are some differences, the biggest one being the normal process whereby primary tooth roots dissolve or, in dental terms, resorb. Root resorption eventually leads to the tooth coming loose to make way for the permanent tooth.
Adult tooth roots can also resorb — but it's decidedly not normal. If adult root resorption isn't promptly treated, it could also lead to tooth loss — but there won't be an incoming tooth to take its place.
Although it can begin inside a tooth, adult root resorption usually begins on the outside. One type, external cervical resorption (ECR), begins around the neck-like area of the tooth not far below the gum line. Its initial signs are small pink spots where the tooth enamel has eroded; those pink cells within the space are doing the damage.
We don't fully understand the mechanism behind ECR, but there are some factors that often contribute. People with periodontal ligament damage or trauma, sometimes due to too much force applied during orthodontic treatment, have a high risk of ECR. Some bleaching techniques for staining inside a tooth may also be a factor.
The key to treating ECR is to detect it as early as possible before it does too much root damage. Regular checkups with x-rays play a pivotal role in early detection. Advanced stages of ECR might require more advanced diagnostics like a cone beam computed tomography (CBCT) scan to fully assess the damage.
If the lesion is small, we can surgically remove the cells causing the damage and fill the site with a tooth-colored filling. If ECR has spread toward the pulp, the tooth's inner nerve center, we may also need to perform a root canal treatment.
Either of these methods intends to save the tooth, but there is a point where the damage is too great and it's best to remove the tooth and replace it with a life-like dental implant or other restoration. That's why it requires vigilance through regular, semi-annual dental visits to detect the early signs of root resorption before it's too late.

A relatively easy and inexpensive way to improve your smile is to whiten your teeth. In fact, you may even be able to do it yourself at home. Although there are differences between at-home and professional whitening, the former can still be effective.
That effectiveness, though, might be dependent on how well you understand what home whitening can do and what it can’t. So before you purchase your kit, here are a few things to know about DIY teeth whitening.
Home kits are safe—when used as directed. Although nothing in life is completely risk-free, home whitening kits are relatively safe. But only if you follow the directions: If you overuse the bleaching solution beyond its intended use, you could wind up with permanent damage to your tooth enamel that can be costly to treat.
Bleaching solutions are relatively mild. Nearly all home kits use carbamide peroxide, a form of hydrogen peroxide, as their bleaching agent. Home kits usually contain no more than 10% of this agent, much lower than professional solutions. Used as directed, this amount of bleaching agent poses little to no risk to dental or general health. On the other hand, the weaker home kit solution does limit the extent of brightness you can achieve compared to stronger professional treatments.
For top results (or certain conditions), consider professional whitening. While you can obtain good results with a home whitening kit, professional whitening provides more precise brightness control and range, and may possibly last longer. That’s because your dentist has more advanced techniques and equipment, as well as stronger bleaching solutions. And, if your discoloration originates inside your teeth, a home kit won’t help—only a dentist can address that kind of discoloration.
Even if you decide to “go solo,” your dentist can still give you advice on what to look for in a home kit, as well as tips for the actual procedure. But whether you whiten at home or let your dentist do it, teeth whitening can take years off your smile and give you a more attractive look.

When things get unpleasant in your mouth, it’s most often related to some underlying cause. In fact, the discomfort you’re feeling is often a call to action to have it checked and treated.
The American Dental Association recently surveyed approximately 15,000 U.S. adults about their oral problems. If you have any of the top 3 problems found in this survey, it could be a “warning bell” sounding in your mouth right now.
Here, then, are the top 3 dental problems in America, what they mean and what you should do about them.
#3: Tooth Pain. About a third of respondents (more among those younger or from lower-income households) indicated pain as a problem. As a warning sign of something wrong, tooth pain could be telling you that you have a decayed tooth, a gum abscess or something similar. The best thing to do is get a checkup as soon as possible. It’s unlikely that whatever is causing the pain will go away on its own and procrastination could make ultimate treatment more complex and difficult.
#2: Difficulty Biting. A slightly higher number of people named difficulty chewing and biting as their main oral problem. As with tooth pain, chewing difficulty causes could be many: cracked, loose or decayed teeth, ill-fitted dentures, or a jaw joint disorder (TMD). Again, if it hurts to chew or bite, see a dentist. Besides the underlying problem, chewing difficulties could also affect the quality of your nutrition.
#1: Dry Mouth. Chronic dry mouth garnered the highest response in the survey, especially among older adults. This is more serious than the occasional “cotton mouth” feeling we all experience—with chronic dry mouth the salivary glands aren’t producing enough saliva to neutralize mouth acid or fight disease, thus increasing your risk for tooth decay or periodontal (gum) disease. It’s most likely caused by medications or systemic conditions, so talk with your dentist or physician about boosting saliva flow.
