What makes our teeth move?

Posted by Dental News Team On December - 2 - 2009

Our body doesn’t like being put under pressure!

You know how it is when you press your thumb to your skin, the area turns white. This is because the blood vessels get squeezed together – leading to a temporary lack of blood, which makes the skin look pale. But it doesn’t matter if you only do this for a few seconds, after that blood circulation starts up again.

Obviously, pressure is bad. Now, the teeth „hang“ in the gums on a system of connective tissue, the desmodont. This desmodont consists of a multitude of little fibers strung up between the root and the bone. The motion of chewing turns into a tugging motion, tugging at the bone, that is!

desmodontTeeth start to move!

Teeth are not permanently set into the bone, they are „moveable“. If e.g. braces put pressure on a tooth, the desmodont can re-group, causing teeth to shift. This is how braces work, although our tongue and face muscles also put pressure on the teeth.

While the teeth tend to move together during adolescence (tertiary narrowing), as the lips and facial muscles continue to get stronger and exert more pressure, after about the age of 50 the opposite happens.

Lip pressure decreases, as does the tightness of the facial muscles (especially in the cheeks) and the tongue ends up exerting more pressure from inside the mouth. Moreover, recession of the gums, whether naturally or due to some illness (such as periodontosis) and the accompanying loss of bone, as well as  osteoporosis, means that the teeth are no longer as securely anchored in the jaw.

The front teeth start to fan out!

All of these factors cause the front teeth to slowly start to fan out. The teeth push forward, causing gaps to form. The longer this goes on, the quicker teeth start to shift, until the patient finally notices this and goes to a dentist.

Aligners are very effective in treating this displacement!

Teeth braces – questions and answers…

Posted by Dental News Team On October - 23 - 2009

Nowadays braces are a widely used instrument to correct faulty tooth placement.

Nevertheless there are some frequently asked questions to know…

Do braces only correct displacements or are there some more benefits?

Only very few people know, that braces can also prevent tooth loss.

If your gums start receding, this can also be caused by faulty tooth placement – talk to your dentist about this or visit an orthodontist. Sometimes faulty tooth placement can increase the risk of an inflammation of the periodontal apparatus.

Braces and kissing, does that work?

Of course it does! There is no interaction between the braces and the tongues.

What’s about the dental hygiene if I wear braces?

A very important thing to know! With braces you have to brush and clean your teeth efficiently to avoid inflammations. Braces combined with poor dental hygiene can cause parodontitis.

Should you need fixed braces or already have them, then get yourself an oral irrigator, only this can help you get your mouth thoroughly clean!
