Why do teeth move after braces?

Retainers for blog post 27.08.2019

Teeth move all the time

Many people do not realise that teeth are mobile. They are held into the jaw bone by periodontal ligaments. These are not hard like bone, they are elastic. Without these ligaments orthodontic treatment would not be possible as they allow the teeth to move. When the brace is removed, the ligaments remember the original position of the tooth and would allow the teeth to drift back to that position again.

 

General daily wear and tear 

The mouth is the most used part of the body. Eating food can cause the teeth to wear down over time, especially if a bite is out of line. Every time you bite into something or chew your food the teeth will be affected. Every time you talk, your tongue generates a pressure against your teeth. All these things can over time cause your teeth to move.  

 

Changes in the mouth

As we go through life, there can be changes to your teeth which can cause unwanted tooth movement. Things like having a tooth extracted or periodontal problems can cause the teeth to drift and fill spaces that have appeared. The bite can also be affected if an opposing tooth is removed as the tooth above it can move downwards to fill the airspace.  Other factors such as jaw growth, wisdom teeth erupting and ageing can cause changes to occur in the mouth which may affect the position of the teeth.

 

Wearing retainers

When your braces are removed, to prevent unwanted tooth movement it is very important to wear retainers. Braces are used to move the teeth and retainers are used to hold the teeth in position. Without retainers, the teeth will want to move …. which is usually back to how they were at the beginning!

Many patients we treat are having a second or even third course of orthodontic treatment because they have not been told the importance of life long retainers. We place fixed wire retainers behind the upper and lower teeth after orthodontic treatment. We also provide removable retainers which are to be worn 2 nights per week in conjunction with a fixed retainer. If no fixed retainer is fitted, the removable retainers should be worn every night for 6 months, then 3-4 nights per week permanently.
