Teeth Stains

Dear Readers,

In this post I would like to talk about a topic that is of great interest to my patients and I think it affects almost every person.

This is the topic of dental stains.

There are different types of stains and their appearance on the teeth always disturbs people and worsens the appearance of their teeth and smiles.

Dental stains can occur for various reasons.Whatever the reason, they are a major aesthetic problem and disturb the people who have them and are noticeable by the people around.

Some of these stains can be easily removed - just by scaling and polishing, and others by whitening procedures at home or in the office.

There is another group of spots that can not be easily removed. In this case there are some restorative dental procedures that have to be performed to achieve a good aesthetic appearance. These procedures include composite fillings, veneers or crowns. It depends on the type of stains.

There are two types of stains according to their formation - EXOGENOUS and ENDOGENOUS.

Endogenous means that the cause has occurred from the inside during the formation of the teeth. These spots can not be removed simply by scaling and polishing. The reasons are:

1. Antibiotic intake in early childhood when teeth are formed.
Tetracycline is the most popular antibiotic that causes this problem.

2. Another reason is the intake of too much fluoride in childhood. Fluoride products are fluoride tablets, fluorinated water, milk, fluoride toothpaste.
Excessive intake of fluoride leads to a disorder called fluorosis. In my practice, I have seen patients with fluorosis living in places where mineral water sources dominate. The water is rich in fluoride and leads to fluorosis.

Exogenous stains- they are 2 types:

1. The first is called EXTRINSIC stains - they are superficial and are not deep in the teeth. This allows them to be removed by polishing.

They could come from:

-Poor oral hygiene

I must make it clear that the above reasons can lead to external spots only if such substances have been taken for a short time or in small quantities.

Of course, the dental habits of the patient are of great importance.

If these causes have acted for a long time or have been used in large quantities and combined with poor oral hygiene, the tooth structures are affected deeper. We say that these factors are involved in the dental structures.

This type of stain is called INTRINSIC and can not be removed by polishing.

Possible causes of this type of stain are:

-Fluoride intake
-Poor oral hygiene
-Teeth with endodontic treatment
-Teeth with trauma
-Decayed teeth
-Pulpal damage
-Amalgam restorations

Whatever the causes of dental stains, the dentist is the one who will diagnose the problem and suggest the best treatment for each case.

Truly yours,
Dr.Trenkova, DDM
