Some stains can be harder to get rid of others. Read about why some stains remain permanently on teeth and the options available to people who want to get rid of them.

The first thing that people will notice when you walk up to them is your smile and nowadays with the advent of social media, a perfect smile is considered a pre-requisite. There is very little room for teeth that are not perfectly aligned or have stains on them. Most people, in fact, associate stains on the teeth with poor oral hygiene and while that may be true in some cases, it is not even a factor in others. A lot of the time, people have stains on their teeth which are permanent in nature and thus require extensive treatment to correct.

Here are some common causes of permanent stains on the teeth.

Fluoride Stains

Fluoride added to the water source was found to be very effective in reducing the incidence of tooth decay. This led to a lot of dental health projects which advocated the addition of fluoride to community water for the sake of improving dental health. Unfortunately, this had one side effect which was discovered quite a bit later. Fluoride levels above a certain level in the water can cause a disruption in the normal mineralization process of the tooth and lead to the development of staining.

The deciduous teeth (milk teeth) start developing within the first few months of intra-uterine life while permanent tooth buds start developing around birth. This means that high-fluoride water consumed by the mother will have an effect on the first set of teeth while that consumed by the baby itself will affect the permanent dentition.

The result can be whitish discoloration on the surface of teeth, brown discolored pits, a dark color of the teeth and others.

Trauma

Children fall. Often. There is just no way around it. This or any other blow to the teeth can result in damage to the underlying tooth bud. Depending upon the severity of the blow, the resultant damage in the mineralization will be visible once the tooth has erupted into the oral cavity. The discoloration may be a fine line across the tooth or a complete discoloration of the tooth itself.

Infection

Another condition that is referred to as "Turner’s Hypoplasia" is responsible for a single tooth becoming discolored permanently. The main culprit here is an infection from a deciduous tooth that affects the developing tooth bud.

The close proximity of the tooth bud to the deciduous teeth means that any infection spreading into the surrounding tissues from the affected root canals should be taken seriously.

Tetracycline Ingestion

The tetracycline class of antibiotics is completely contraindicated for ingestion in pregnant women as well as those that are still breastfeeding. This drug crosses the placental barrier and has a particular predilection for the hard tissues of the body. Thus, the tetracycline affects the mineralization of the bones and teeth most often.

The kind of stains that are seen due to tetracycline ingestion will be spread across all the tooth buds present in the body at the time. While most people with access to advanced medical facilities are aware and do not take antibiotics during pregnancy, a lot of time the exposure to tetracycline occurs when pregnancy is yet to be confirmed.
