Teeth sensitive, many patients are worry during an orthodontic treatment because their teeth are more sensitive than usual.

Whether it is with traditional braces or with Invisalign, when a new form of pressure is applied on the teeth, this also creates some pressure on the roots which disturbs the blood flow in the dental alveolus.

The outcome is some inflammation in the pressure zone and that is why the teeth will be able to move.

The inflammation calls for restructuring cells to the rescue. One type of these cells are named osteoclasts and they deconstruct bone tissues, while on the other side of the root, the osteoblast cells will restructure it. During this inflammatory phase, your teeth will be more sensitive than usual.

The pain is temporary and is less and less painful as the treatment progresses.

This is why your teeth seem to be wobbly when you eat or when you brush them. The periodontal ligament thickens and the fibres that hold your teeth in place are elastic.

Once the treatment is completed, it will take a few months for the ligament to relax. Your teeth mobility will disappear. This is why a stabilizing device is necessary after an orthodontic treatment.
