Why Are My Teeth Translucent?

Key Takeaways

• Translucent teeth are a sign of enamel erosion
• Enamel erosion is a condition in which the protective layer of your teeth weakens
• It's typically caused by acidic food and drink, as well as other underlying issues
• Enamel erosion is often an early indication of tooth decay and gum disease

7 Possible Causes of Translucent Teeth

Translucent teeth are caused by tooth erosion, which typically occurs when acids dissolve tooth enamel. Tooth enamel is a hard, white substance that covers the crown of your tooth and protects teeth from decay and infection.

When enamel is damaged, teeth can look transparent or translucent. Other signs of dental erosion include:

• Transparency along the biting edges
• Loss of tooth surface leading to a smooth or shiny apperance
• Sensitivity to hot, cold, or sweet foods and drinks
• Yellowing or darkening
• Exposed or visible dentin

Other conditions that can weaken your enamel and make your teeth look translucent include:

1. Celiac Disease

Celiac disease is a chronic autoimmune disorder that affects an estimated 2 million Americans.¹ It's caused by consuming gluten, resulting in a wide range of gastrointestinal symptoms.

People with celiac disease often have translucent teeth. This is because the disease affects dental health and the enamel coating.

2. Enamel hypoplasia

Enamel hypoplasia is a genetic condition that can cause tooth decay and premature tooth loss. It occurs due to a lack of tooth mineralization, which thins the enamel. Enamel hypoplasia leaves these areas susceptible to caries (tooth decay) and fractures.²

3. Acidic erosion

Acidic erosion wears down teeth surfaces, weakening and damaging the enamel.³ This is typically caused by the highly acidic external and internal sources, such as:

• fruit juices
• soft drinks
• sports and energy drinks
• citrus fruits
• vinegar
• alcohol
• Excessive vomiting
• Gastric reflux from gastroesophageal reflux disease (GERD)
• Reduced saliva production

The measure of acidity in foods and drinks is called the pH level. Loss of tooth enamel happens when the pH level is under 4.0.

For comparison, water has a pH level of 7.0. Many sour sweets, for example, have a pH level of 3.0 and under. These can weaken and wear away tooth enamel, leading to translucence. ⁴

4. Xerostomia (dry mouth)

Saliva neutralizes acids from foods and beverages. Xerostomia is a condition where the saliva does not flow well. Various factors can cause this, such as:

• Medications
• Disease
• Side effects of certain drugs
• Certain medical conditions

Experts refer to xerostomia as dry mouth syndrome. Dry mouth syndrome can lead to malnutrition, dehydration, tooth decay, and gum disease.

People with this condition may also experience cracked lips and dry skin. It can cause serious problems in the body that are not easily visible.⁶

5. Acid reflux 

Acid reflux is a disorder in which highly corrosive stomach acid flows into the esophagus. This causes heartburn and difficulty swallowing. An abnormal motion of the lower esophageal sphincter also causes acid reflux.⁷

Enamel may wear down over time due to frequent exposure to stomach acid, which the stomach uses to break down food. If left untreated, acid reflux can develop into gastroesophageal reflux disease (GERD), a more severe version of acid reflux.

6. Brushing too hard

Brushing too hard isn’t immediately noticeable, but it will cause enamel erosion over time. Brushing too aggressively or with a hard-bristled toothbrush can still damage teeth. Brushing aggressively also doesn't necessarily make your teeth cleaner. 

7. Frequent vomiting

Frequent vomiting, such as that caused by morning sickness or eating disorders, can expose acid to your teeth. When this happens, the highly corrosive stomach acid wears away the tooth’s surface. This causes enamel erosion.

Can You Prevent Tooth Translucence? 

You cannot prevent some causes of translucent teeth. This includes celiac disease and enamel hypoplasia. However, you can manage other conditions to prevent the enamel from thinning. Here are some tips:

• Using a straw — Using a straw helps avoid erosion caused by acidic beverages
• Wait before brushing — Waiting at least 30 minutes after eating or drinking acidic food and drinks can help prevent further enamel erosion
• Dietary changes — Avoiding sugary foods and drinks limits acidic erosion damage to your teeth

How to Remineralize Teeth

Tooth remineralization is a process where minerals, such as calcium and phosphate, replace the tooth enamel. You can remineralize your teeth using specialized products from your dentist.

Some methods to remineralize your teeth include:

• Brushing teeth with specialized toothpaste
• Fluoride treatments
• Drinking fluoridated water
• Eating foods rich in calcium and phosphate

Tooth remineralization also helps prevent cavities and restores shine to teeth.⁸

How to Fix Translucent Teeth

Fixing translucent teeth is not always possible because enamel loss is irreversible. Once enamel is lost, it will not reform.⁹

However, there are ways to prevent enamel from eroding further. Some treatments can even restore the appearance of teeth. Most of the time, restoring the teeth is a purely cosmetic issue.

Professional Treatment Options

Professional treatments that can restore the look of your teeth include:

• Bonding — Dentists apply composite resin to the teeth, which remedies the cosmetic issues of translucent teeth. The resin also leaves a protective layer on the teeth, preventing enamel erosion from worsening.
• Dental crowns — Crowns protect and strengthen tooth structure, and your dentist may recommend them if you have severe tooth erosion.
• Veneers — Dental veneers are thin porcelain shells cemented onto the front of your teeth, giving a uniform look.^{10, 11}

Natural Remedies

There are also natural remedies that you can try to reduce damage to your teeth, include:

• Managing acid reflux — People with acid reflux should avoid acidic foods and drinks or take medications when needed to prevent acid reflux symptoms.
• Schedule regular dental cleanings — Visiting your dentist every 6 months for check-ups and cleanings maintains your oral health.
• Increasing saliva — Chewing on sugar-free gum can increase saliva production, which helps prevent acids from damaging enamel.
• Boost water intake — Drinking plenty of water washes away acids in your mouth after eating and drinking. It can also thin saliva, allowing it to flow freely, which helps protect the teeth.
