Although distressing to many parents, infants and toddlers sucking their thumb is a common if not universal habit. Most children phase out of it by around age 4, usually with no ill effects. But thumb-sucking continuing into late childhood could prove problematic for a child’s bite.
Thumb sucking is related to how young children swallow. All babies are born with what is called an infantile swallowing pattern, in which they thrust their tongues forward while swallowing to ensure their lips seal around a breast or bottle nipple when they nurse. Thumb-sucking mimics this action, which most experts believe serves as a source of comfort when they’re not nursing.
Around 3 or 4, their swallowing transitions to a permanent adult swallowing pattern: the tip of the tongue now positions itself against the back of the top front teeth (you can notice it yourself when you swallow). This is also when thumb sucking normally fades.
If a child, however, has problems transitioning to an adult pattern, they may continue to thrust their tongue forward and/or prolong their thumb-sucking habit. Either can put undue pressure on the front teeth causing them to move and develop too far forward. This can create what’s known as an open bite: a slight gap still remains between the upper and lower teeth when the jaws are shut rather than the normal overlapping of the upper teeth over the lower.
While we can orthodontically treat an open bite, we can minimize the extent of any treatments if we detect the problem early and intervene with therapies to correct an abnormal swallowing pattern or prolonged thumb sucking. For the former we can assist a child in performing certain exercises that help retrain oral and facial muscles to encourage a proper swallowing pattern. This may also help diminish thumb sucking, but we may in addition need to use positive reinforcement techniques to further discourage the habit.
To stay ahead of possible problems with thumb sucking or the swallowing pattern you should begin regularly taking them to the dentist around their first birthday. It’s also a good idea to have an orthodontic evaluation around age 6 for any emerging bite problems. Taking these positive steps could help you avoid undue concern over this common habit.

If you’ve noticed some of your teeth seem to be “longer” than you remembered, it’s not because they’ve grown. Rather, your gums have shrunk back or receded to expose more of the underlying tooth.
It’s not just unattractive — gum recession could lead to severe consequences like bone or tooth loss. But before we begin treatment we need to find out why it happened. Knowing the true cause will help us put together the right treatment plan for your situation.
Here are 4 of the most common causes for gum recession and what we can do about them.
The kind of gum tissues you have. There are two kinds of risk factors: those you can control and those you can’t. Because you inherited the trait from your parents, your gum tissue thickness falls into the latter category. Although there are degrees within each, gum tissues are generally classified as either thick or thin. If you have thin tissues, you’re more susceptible to gum recession — which means we’ll need to be extra vigilant about caring for your gum health.
Tooth position. Normally a tooth erupts during childhood in the center of its bony housing. But it can erupt outside of it, often resulting in little to no gum tissue growth around it. The best solution is to move the tooth to a better position within the bony housing through orthodontics. This in turn could stimulate gum growth.
Over-aggressive brushing. Ironically, gum recession could be the result of brushing, one of the essential hygiene tasks for dental health. Consistently brushing too hard can inflame and tear the tissues to the point they begin to recede. Brushing doesn’t require a lot of force to remove plaque: use gentle, circular motions and let the detergents and mild abrasives in your toothpaste do the rest.
Periodontal (gum) disease. This, by far, is the greatest cause for gum recession: an infection caused by built-up bacterial plaque. The weakened tissues begin to detach from the teeth and recede. Gum disease can be treated with aggressive plaque removal and supporting techniques; but it’s also highly preventable. Practicing daily brushing and flossing and regularly visiting your dentist for thorough cleanings and checkups are the best practices for keeping your gums as healthy as possible.
