What causes mottled teeth – Causes and Cure

A mottled tooth is a condition characterised by discolouration of the teeth. The enamel, the outermost layer of the teeth, is seen with some irregular white or brown spots. This condition is called dental fluorosis; the affected teeth are called mottled teeth. In mild to moderate cases of fluorosis, it is only a case limited to aesthetics. However, in severe cases of fluorosis, it affects the structural durability of the teeth. There are various causes of mottled teeth. If you are also wondering what causes mottled teeth, read the information provided below for more – brought to you by Smayate Dental Clinic.

What causes mottled teeth?

Fluoride is a beneficial mineral for your teeth when consumed in suitable amounts. It helps in strengthening the enamel and prevent tooth decay. Excessive exposure to fluoride during the developmental stage of permanent teeth can lead to mottled teeth. There can be several ways by which there is excessive consumption of fluorides, and some of the common ways are discussed below.

Water fluoridation

Water fluoridation is a technique adopted by public health bodies to regulate fluoride consumption by people at mass. However, excessive fluoride consumption can happen if the fluoride mixed in the community water supply needs to be regulated properly by the concerned authorities.


Fluoride-containing toothpaste is suggested for the prevention of caries and stronger teeth. However, small children who can not spit out the paste properly have a high risk of ingestion. 

Natural Water Sources

In certain geographic regions, natural water sources may contain elevated fluoride levels. People who rely on such water sources for drinking and cooking may experience higher fluoride exposure.

Fluoride Products

Besides toothpaste, other fluoride products, such as mouth rinses or fluoride gels used in dental treatments, can contribute to overall fluoride intake. Accidental swallowing of these products can occur, especially in children.

Environmental Exposure

In some cases, exposure to industrial pollutants or environmental sources of fluoride may contribute to overall fluoride intake. This is more likely in areas with certain industrial activities.

Treatment options  

Dental Bonding

Bonding is a simple procedure for applying a tooth-coloured composite material to the affected tooth. The resin material is directly applied to the tooth without altering the original structure. The composite material is shaped according to the natural tooth. It is an effective way to enhance your smile.


Porcelain veneers are thin shells directly applied to the teeth’ front surface. Porcelain veneers are highly durable and long-lasting solutions for smile enhancement. Veneers are made in a dental lab and are an effective way of treatment.


It is a simple technique that removes weak and thin enamel using chemicals. It is a safe way to manage the intrinsic staining of mottled teeth. Microabrasion can also be combined with other cosmetic treatments like teeth whitening to produce more effective results. 

Dental Crowns

Crowns or dental caps are indicated in severe cases of tooth damage. Dental crowns provide the necessary strength, structural durability, and smile enhancement.
