Could excess iron levels be causing my tooth decay?

Yes: Get into your dentist and disk treatment and preventive options.

Not Likely: Unless you are sucking on a sugar based source of iron, iron supplements are generally swallowed and not a source of increased decay. If you have dry mouth associated with the reason for your iron deficiency, then the dry mouth condition can increase decay.

Iron and teeth: Excessive iron in the body does not lead to increased decay. We can see discoloration occur when iron levels are high in young children as the iron incorporates into the developing teeth. Once the teeth are erupted iron will not affect them.

Probably not: High iron levels have not been shown to be a cause of tooth decay. Tooth decay is a bacterial process enabled by food debris left around the teeth.

Bacteria and sugar: Decay is caused by bacteria which are naturally occurring in your mouth. When the bacteria are fed sugar, either simple like sweets or complex like bread or sugar, they produce acid which eats into the tooth.
