Why Do White Spots Appear on Teeth and How to Remove Them

Prevention is more affordable than treatment.

Understanding White Spots on Teeth

White spots on teeth represent areas where the enamel has defects.

Enamel is a thin yet incredibly hard outer layer of the tooth, primarily composed of calcium phosphate, making it the strongest tissue in the human body. When enamel development is disrupted or it begins to deteriorate, the mineral content decreases, resulting in zones of demineralization beneath the surface. These areas reflect light differently from healthy enamel, appearing as white spots.

Causes of White Spots on Teeth

Demineralized patches often result from acid exposure but can also be present when teeth first emerge. Several factors can contribute to this condition.

Poor Oral Hygiene

Bacteria break down carbohydrates and produce acids that penetrate and weaken the enamel's surface. Without regular plaque removal, enamel damage progresses, potentially leading to cavities.

This issue is especially common among children and individuals wearing braces or other fixed orthodontic appliances.

Excessive Sugar Intake

Frequent consumption of sugary foods increases acid production by bacteria, accelerating calcium loss and causing white spots that may eventually develop into cavities.

Dental Fluorosis

Fluorosis is a cosmetic enamel defect typically seen in children under eight who have ingested excessive fluoride through diet or dental products. During tooth formation, specialized cells called ameloblasts create enamel, but high fluoride levels can kill these cells, affecting only unerupted teeth. Once teeth have erupted, fluoride no longer causes fluorosis.

Mild fluorosis appears as small white spots, while severe cases show white, light brown, or dark brown patches, along with surface irregularities and pits.

It's important to use fluoride toothpaste cautiously in children, ensuring they spit it out and do not swallow, as fluoride remains essential for cavity prevention.

Enamel Hypoplasia

Enamel hypoplasia is a developmental defect where enamel formation is disrupted during tooth development, often before birth or in early infancy. Causes include:

• Congenital conditions such as hypoparathyroidism, Usher syndrome, Seckel syndrome, among others.
• Vitamin D deficiency during pregnancy.
• Maternal smoking during pregnancy.
• Use of certain medications like antiepileptics during pregnancy.
• Trauma.
• Infections such as respiratory viruses, ear infections, chickenpox, or urinary tract infections in infancy.

This condition can result in white spots, pits, or grooves on teeth.

Adhesive Residue After Orthodontic Treatment

Fixed orthodontic devices like braces are bonded with special adhesives that can harbor bacteria producing acid, leading to enamel damage. Areas where adhesive is uneven or protruding can accelerate demineralization and white spot formation. Maintaining excellent oral hygiene and regular dental check-ups are crucial.

Gastroesophageal Reflux Disease (GERD)

GERD causes stomach acid to flow back into the esophagus and sometimes into the mouth, especially during sleep. Frequent acid exposure erodes enamel, resulting in white spots.

Bulimia

This eating disorder involves recurrent binge eating followed by self-induced vomiting, exposing teeth to stomach acid repeatedly. This acid attack leads to enamel demineralization and white spots. Frequent vomiting can also damage the valve between the stomach and esophagus, worsening acid reflux and dental erosion.

How to Remove White Spots on Teeth

If the white spots are purely cosmetic, as in fluorosis, they can be masked. If they indicate early decay, enamel remineralization is necessary. Consulting a dentist is essential to determine the best treatment option.

Microabrasion

This technique polishes the enamel surface, removing a thin layer and smoothing the tooth. Calcium phosphate then fills in gaps between enamel particles, strengthening it.

Fluoride Treatment

High-concentration fluoride is applied directly to white spots. Dentists may also recommend calcium phosphate-containing products to enhance results.

Teeth Whitening

Whitening treatments can camouflage white spots by lightening the surrounding healthy enamel, evening out tooth color.

Veneers

Veneers are thin shells that cover the tooth surface, ideal for severe fluorosis cases where other treatments fail. They offer immediate aesthetic improvement and durability but are costly.

Preventing White Spots on Teeth

Prevention is simpler and more cost-effective than treatment. Here are key steps:

Maintain Regular and Thorough Oral Hygiene

Reducing bacteria that produce acid requires timely plaque removal. Electric toothbrushes are highly effective, complemented by antimicrobial mouth rinses.

Brush at least twice daily, and after every meal if wearing braces. Professional dental cleanings should be scheduled as advised.

Use Fluoride Gels and Varnishes

Applying fluoride-containing products two to four times annually boosts enamel protection beyond daily toothpaste and rinses.

Use Products Containing Casein Phosphopeptide-Amorphous Calcium Phosphate (CPP-ACP)

These milk protein complexes supply calcium phosphate to enamel and reduce acidity. Available as creams to apply after brushing, they should remain undisturbed (no eating or drinking) for at least 30 minutes to maximize benefits.
