What Your Habits are doing to Your Teeth

It’s common for young children to put anything and everything into their mouths. This curiosity is normal, and unless it develops into bad habits that carry into later childhood, is beneficial to development. Habits like nail-biting, thumb sucking, using a pacifier excessively, and tongue thrusting as you swallow all have negative long-term effects on your oral health. 

 

Thumb Sucking and Excessive Pacifier Use

Children are born with a natural sucking reflex, which is why they tend to gravitate towards thumb sucking or get attached to a pacifier as a self-soothing tool. This impulse disappears around the four-month mark, but most children keep the habit for much longer. This is natural, and most children end up growing out of any habitual thumb sucking or pacifier use by age four at the latest. Stopping this habit by age four is ideal, and usually results in no long-term orthodontic issues. 

The pressure applied to teeth through the continuous sucking motion can cause issues with tooth positioning and the growth of the jaw bones. This can later manifest in an openbite, buck teeth, or underdeveloped lower jaw and chin. 

Orthodontists usually recommend that children and parents work to break these habits on their own before treatment starts. If this proves ineffective, there are appliances that an orthodontist can install that make thumb sucking and self-soothing less pleasurable for the child. 

 

Tongue Thrusting

Like thumb sucking, the anatomical reasoning for tongue thrusting should cease on its own. Tongue thrusting has to do with how someone swallows. When young children swallow, their tongues push against their teeth, as they grow older this should transition to the tongue applying pressure to the roof of the mouth during the swallowing process. 

Some people never grow out of swallowing with their tongue on their teeth. This is what orthodontists refer to as tongue thrusting, or more formally orofacial muscular imbalance. Tongue thrusting eventually causes tooth displacement and an openbite. Oftentimes other non-orthodontic underlying issues must be addressed before orthodontic treatment can become effective. 

These underlying issues must continue to be treated beyond orthodontic treatment as well to maintain the work your orthodontist has done. This of course means wearing your retainer, but also means that your dentist or another doctor may address a second issue with you. 

 

Nail Biting

Nail biting is another common bad habit in children and teens. While it certainly isn’t a good habit to keep up because of the dirt and germs residing under your nails, there are many more negative effects. 

Biting your nails is bad for your general and oral health because you’re introducing bacteria and dirt into your mouth. The germs and grime you ingest while biting your nails can cause illness and the consistent biting is hard on your enamel. 

Chewing your nails results in unnecessary wear on your teeth. It weakens the enamel and can even lead to chipping or the teeth becoming crooked. When you have braces, chewing your nails slows down orthodontic treatment. In addition to weakening the roots and making the teeth susceptible to movement, biting your nails can also displace brackets and wires. This makes your braces less effective and can result in more appointments to fix appliances or brackets.
