Along with thumb sucking, childhood teeth grinding is one of the top concerns anxious parents bring to their dentists. It’s so prevalent, though, many providers consider it normal behavior—the sleep-disturbing sound it can generate is often the worst consequence for the habit.
But that doesn’t mean you should brush aside all concern, especially if the habit continues into late childhood. Long-term teeth grinding could eventually damage the teeth and gums.
Teeth grinding (or clenching) is the involuntary movement of the jaws when not engaged in normal functions like chewing, speaking or swallowing. The action often produces higher than normal chewing forces, which over time can accelerate tooth wear, cause fractures, or contribute to loose teeth, all of which could increase the risk of dental disease. While it can occur at any time it’s most common among children during nighttime sleep.
While stress is the usual trigger for teeth grinding in adults, with young children the causes for the habit are more complex and less understood. Most doctors hold to the theory that most pediatric teeth grinding arises during shifts from lighter to heavier, rapid-eye-movement (REM) sleep. The child’s immature neuromuscular chewing control may engage involuntarily during this shift. Teeth grinding is also prevalent among children who snore or mouth-breathe, or who take anti-depressant medication.
But as mentioned before, there’s usually no cause for concern unless the habit persists beyond about age 11. If the habit isn’t fading, you should speak to your dentist about ways to reduce it or its effects. One way is with a custom-made night guard worn during sleep. The smooth, plastic surface of the appliance prevents teeth from making solid contact with each other during a grinding episode.
You might also seek treatment from an ear, nose and throat (ENT) specialist if your child is having issues with airway obstruction, which could also relieve teeth grinding. And children experiencing stressful situations or events may find relief both emotionally and physically from psychological therapy.
At younger ages, you can safely regard your child’s grinding habit as normal. But if it persists, it’s worth looking for ways to reduce it.

There's something universal about thumb sucking: nearly all babies do it, and nearly all parents worry about it. While most such worries are unfounded, you should be concerned if your child sucks their thumb past age of 4 — late thumb sucking could skew bite development.
Young children suck their thumb because of the way they swallow. Babies move their tongues forward into the space between the two jaws, allowing them to form a seal around a nipple as they breast or bottle feed. Around age 4, this “infantile swallowing pattern” changes to an adult pattern where the tip of the tongue contacts the front roof of the mouth just behind the front teeth. At the same time their future bite is beginning to take shape.
In a normal bite the front teeth slightly overlap the bottom and leave no gap between the jaws when closed. Â But if thumb sucking continues well into school age, the constant pushing of the tongue through the opening in the jaws could alter the front teeth's position as they erupt. As a result they may not fully erupt or erupt too far forward. This could create an open bite, with a gap between the upper and lower teeth when the jaws are closed.
Of course, the best way to avoid this outcome is to encourage your child to stop thumb sucking before they turn four. If, however, they're already developing a poor bite (malocclusion), all is not lost — it can be treated.
It's important, though, not to wait: if you suspect a problem you should see an orthodontist for a full evaluation and accurate diagnosis. There are even some measures that could discourage thumb sucking and lessen the need for braces later. These include a tongue crib, a metal appliance placed behind the upper and lower incisors, or exercises to train the tongue and facial muscles to adopt an adult swallowing pattern. Often, a reward system for not sucking their thumbs helps achieve success as well.
Thumb-sucking shouldn't be a concern if you help your child stop before age 4 and keep an eye on their bite development. Doing those things will help ensure they'll have both healthy and straight teeth.

A tooth with deep decay is in real peril. If the disease isn’t stopped, it can eventually infect the bone and greatly increase the risk of losing the tooth. But tooth decay removal and a root canal treatment can stop advancing decay and resulting infection in its tracks.
During this common procedure we first drill into the tooth to access the inner pulp. After removing the infected pulp tissue, we disinfect and fill the empty chamber and root canals with gutta percha. We then seal the tooth and crown it to protect against re-infection.
But while most root canals are successful and long-lasting, sometimes the tooth becomes re-infected. Here are 3 factors that could affect the long-term success of a root canal treatment.
Early treatment. Like many health problems, the sooner we detect decay and treat it, the better the outcome. A tooth in which the infection has already advanced beyond the pulp is at greater risk for re-infection than one in which the infection is localized in the pulp. Keeping up your regular dental visits as well as seeing the dentist at the first sign of abnormality—spots on the teeth or pain—can increase your chances of early diagnosis.
Tooth complications. Front teeth with their single roots and canals are much easier to access and treat than a back molar with an intricate root canal network. Root canals can also be extremely narrow making them easy to miss during treatment. In cases like this the expertise and advanced equipment of an endodontist (a specialist in root canal treatment) could help increase the odds of success in complex situations.
The aging process. Teeth do wear over time and become more brittle, making them increasingly susceptible to fracture. A previous root canal treatment on an aging tooth might also increase the fracture risk. To avoid this, it’s important for the tooth to receive a crown after the procedure to protect the tooth not only from re-infection but undue stress during chewing. In some situations, we may also need to place a post with a bonded composite buildup within the tooth to give it extra support.
Even if a tooth has these or similar complications, a root canal treatment may still be advisable. The benefits for preserving a decayed tooth often far outweigh the risks of re-infection.
