How to Repair Tooth Enamel and Prevent Acid Erosion

Q: What Causes Teeth to Lose Enamel?

Enamel can wear away for a variety of reasons, but one of the most common causes of tooth enamel loss is erosion caused by acidic foods and drinks. These acids attack your tooth enamel, wearing away the minerals that keep it strong, which is why you should protect your enamel. Typical signs of tooth enamel loss are: Discolored, yellowing teeth, Rounded edges to your teeth (due to surface loss), Tooth pain or sensitivity. Acids weaken tooth enamel over time but, thankfully, it is possible to encourage weakened tooth enamel repair. This process is called remineralization.

Enamel is the hard outer surface of your tooth that protects the dentin and other inner layers underneath.¹ Because tooth enamel contains no living cells, once it’s gone, your body can’t repair damage from enamel wear on its own.¹ The good news is that it’s possible to repair enamel and prevent dental erosion with a good oral care routine and diet.²

Learn more about how you can help strengthen your enamel to prevent erosion below.

What Causes Teeth to Lose Enamel?

Enamel can need repairing for a variety of reasons, but one cause of tooth enamel loss is acid erosion caused by certain acidic foods and drinks.² These acids attack your tooth enamel, wearing away the minerals that keep it strong, which is why you should protect your enamel.²

Typical signs of tooth enamel loss are:²

Discolored, yellowing teeth
Hollows in your teeth and wearing away of the tooth surface and biting edges
Tooth pain or sensitivity

Acid erosion can weaken tooth enamel over time but, thankfully, it is possible to encourage weakened tooth enamel to strengthen and actively repair itself in a process called remineralization.³

How Does Tooth Remineralization Work?

Think of your mouth as a battleground between the ‘bad guys’ – the acids that remove minerals from tooth enamel in a process called demineralization – and the ‘good guys’ – saliva, your body’s natural defense against acid erosion. Saliva, which contains minerals such as calcium and phosphate, helps to repair enamel and reverse microscopic acid damage in a process called ‘remineralization’.⁴

How to Repair Tooth Enamel and Prevent Tooth Enamel Erosion

Tooth Enamel Repair – Fact vs Fiction:

FACT: Drink more water. Drinking water with fluoride helps prevent tooth decay.⁴
FACT: Chew sugar-free gum after eating. Chewing gum is a great tool to help weakened tooth enamel repair because it boosts that all-important saliva production.⁴ Be sure to look for sugar-free gums with the ADA Seal of Acceptance.
FACT: Consume soda and soft drinks in moderation. These beverages are highly acidic and can wear away enamel.⁴
FICTION: Brush your teeth immediately after eating. Wait one hour after having any acidic foods or drinks before you brush. This will give your teeth time to build up their mineral content and repair your enamel.² Ideally, use an enamel-strengthening toothpaste such as Pronamel Intensive Enamel Repair Extra Fresh. Pair your Pronamel toothpaste with our Intensive Enamel Repair Mouthwash for that actively repairs acid-weakened enamel beyond brushing alone.
FACT: Dairy and fiber-rich fruits and vegetables are good for teeth. Fiber-rich foods don’t just help to keep your teeth and gums clean, they also help to increase essential saliva flow.⁴ The calcium and phosphates in dairy products like milk, cheese and yogurt can help to remineralize and rebuild your acid-weakened enamel.⁴
FACT: Use a soft toothbrush when brushing your teeth. Use a soft-bristled toothbrush and brush gently twice a day for at least two minutes.²
FACT: Pronamel toothpaste protects against the effects of enamel erosion and helps to strengthen acid-weakened tooth enamel.* Pronamel helps rebuild enamel strength. Pronamel is the number one dentist-recommended brand for strengthening and protecting enamel.
