Yes, acid reflux can damage your teeth. When stomach acid reaches the mouth again and again, it softens and dissolves enamel, a process called dental erosion, which can lead to sensitivity, yellowing, thin or chipped edges and cupped-out chewing surfaces. Occasional heartburn rarely causes visible harm, but frequent reflux or GERD, especially at night, is a common and serious cause of tooth wear, and it’s often a dentist who notices it first during a general dentistry exam.
Some people with reflux never feel heartburn at all. This “silent reflux” can still bathe the back teeth in acid while they sleep. The first clue is sometimes a dentist pointing out wear that doesn’t match a person’s diet or habits.
At our top dental office in Oakville, we look at tooth wear as a health signal, not just a cosmetic issue. That’s the heart of complete health dentistry.
Once enamel is lost, it doesn’t grow back, but it can be protected and rebuilt with bonding, crowns and bridges or other restorations. Reflux is also closely linked with sleep-disordered breathing, which is why sleep apnea management can be part of the picture. You can book an appointment for an erosion check anytime.
Definition
Dental erosion is the chemical loss of tooth enamel caused by acid that doesn’t come from bacteria. Sources include stomach acid from reflux or vomiting and acidic foods and drinks. Unlike cavities, erosion often affects wide, smooth areas of many teeth.
How does reflux damage teeth?
Enamel begins to dissolve when the mouth’s pH drops below about 5.5. Stomach acid is far stronger, with a pH that can be around 1 to 2.
When reflux reaches the mouth, it softens enamel. If it happens often, especially during sleep when saliva flow is low, there isn’t enough time for the enamel to recover. Over months and years, it thins.
Signs of acid erosion from reflux
- Sensitivity to cold, hot or sweet foods
- Teeth looking more yellow as enamel thins and dentin shows
- Smooth, shiny or “glassy” surfaces
- Thin, see-through or chipped edges on front teeth
- Small dips or cups on the chewing surfaces of back teeth
- Fillings that seem to stand above the tooth surface
- Wear on the tongue side of upper teeth, a classic reflux pattern
- Sour taste, burping, hoarse voice or morning sore throat
Erosion vs cavities vs grinding
| Acid erosion | Cavities | Grinding (attrition) | |
|---|---|---|---|
| Cause | Acid from reflux, vomiting or diet | Acid from plaque bacteria | Tooth-on-tooth wear |
| Look | Smooth, broad, shiny surfaces, cupping | Dark spots or holes in specific areas | Flat, worn edges that match opposing teeth |
| Typical location | Tongue side of upper teeth, molar chewing surfaces | Grooves, between teeth, gumline | Biting edges and chewing surfaces |
| Pain | Sensitivity | Sensitivity or toothache | Jaw soreness, sensitivity |
Many people have more than one of these at once. Reflux and grinding often happen together, especially in people with sleep apnea.
What causes reflux in the first place?
- A weak valve between the stomach and esophagus
- Large or late meals
- Alcohol, caffeine, chocolate, spicy and fatty foods
- Smoking
- Pregnancy and extra body weight
- Some medications
- Obstructive sleep apnea, which is strongly linked with night-time reflux
How is reflux erosion treated?
Step 1: Address the reflux
Your dentist may recommend seeing your family doctor. Medical treatment and lifestyle changes reduce how often acid reaches your mouth. Treating the cause comes first.
Step 2: Protect what’s left
- Prescription-strength fluoride toothpaste
- Fluoride varnish at dental visits
- Remineralizing products with calcium and phosphate
- A custom tray to hold fluoride gel, in some cases
Step 3: Restore damaged teeth
- Composite bonding for small areas of wear
- Veneers for worn front teeth
- Onlays or crowns for back teeth with significant wear
- CEREC same-day restorations to rebuild worn teeth in fewer visits
Traditional crowns vs CEREC for worn teeth
| Traditional crown | CEREC same-day crown | |
|---|---|---|
| Visits | 2, about 2 weeks apart | 1 |
| Temporary crown | Yes | No |
| Impressions | Often trays and putty | Digital scan |
| Good for | Complex, multi-tooth cases | Most single worn teeth |
What to do right after a reflux episode
- Rinse with water or a mix of water and a little baking soda to neutralize acid.
- Don’t brush right away. Enamel is soft after an acid attack. Wait about 30 to 60 minutes.
- Chew sugar-free gum to boost saliva, which helps buffer acid.
- Use fluoride toothpaste when you do brush.
Safety note: Frequent heartburn, trouble swallowing, chest pain, unexplained weight loss or vomiting blood need medical attention, not just dental care. Talk to your family doctor about reflux symptoms. Chest pain should always be treated as a possible emergency.
Daily habits that protect enamel
- Avoid eating within 2 to 3 hours of bedtime
- Raise the head of your bed slightly if night reflux is a problem
- Sip acidic drinks with meals instead of all day
- Drink water through the day
- Use a soft toothbrush and gentle pressure
- Limit soda, sports drinks, citrus juice and wine
- Get screened for sleep apnea if you snore or wake up tired
What happens at your first erosion assessment?
- Health history. Reflux symptoms, diet, medications, sleep and snoring are discussed.
- Close exam. Each tooth is checked for wear patterns, thin edges and cupping.
- Photos and scans. Digital records let us track wear over time.
- Bite check. Grinding and clenching are assessed, since they speed up wear on softened enamel.
- Sleep screening if needed. A home sleep test may be suggested when snoring or fatigue are part of the picture.
- Plan. Protection, monitoring and any restorations are explained, plus when to involve your doctor.
How acidic are common foods and drinks?
| Item | Approximate pH | Enamel risk |
|---|---|---|
| Stomach acid | About 1 to 2 | Very high |
| Lemon juice | About 2 | Very high |
| Cola | About 2.5 | High |
| Sports drinks | About 3 | High |
| Orange juice | About 3.5 | Moderate to high |
| Coffee | About 5 | Lower |
| Milk | About 6.5 to 7 | Low |
| Water | About 7 | None |
Enamel starts to soften below about pH 5.5. Adding acidic drinks on top of reflux increases the total acid exposure your teeth face.
Can children’s teeth be damaged by reflux?
Yes. Children with reflux, frequent vomiting or a habit of sipping juice and sports drinks can show erosion early, since baby teeth have thinner enamel. Signs include sensitivity, yellowing and rounded, worn-looking teeth. Mention any reflux history at your child’s checkup so the dentist can watch for it.
Common mistakes people make
- Brushing hard right after reflux or vomiting
- Using whitening toothpastes on eroded teeth
- Treating sensitivity without asking why it started
- Ignoring night-time symptoms like sour taste or hoarseness
- Waiting until teeth chip to get them checked
Myths about reflux and teeth
Myth: Only people with heartburn have reflux damage
Silent reflux can damage teeth without classic heartburn.
Myth: Enamel grows back
Enamel doesn’t regenerate. Early softening can partly remineralize, but lost enamel is gone.
Myth: Yellow teeth just need whitening
If teeth are yellow because enamel is thin, whitening won’t fix it and can increase sensitivity.
Myth: Erosion is only cosmetic
Severe erosion can cause pain, broken teeth and bite changes.
How reflux connects to overall health
Reflux, sleep apnea, poor sleep and tooth wear often show up together. Treating one can help the others. For example, treating sleep apnea can reduce night-time reflux in some people.
This whole-body view is what complete health dentistry is about: using what we see in the mouth to support your wider health.
Patient scenarios
The sensitive back teeth. A 42-year-old has sensitive molars with small cups on the chewing surfaces. He doesn’t have heartburn but often wakes with a sour taste. His physician confirms reflux, and fluoride treatment plus bonding protects his teeth.
The snorer with wear. Another patient has worn teeth, snores and wakes tired. A home sleep test leads to a sleep apnea diagnosis, and treating it improves her night-time reflux too.
The chipped edges. A third patient’s front teeth look thin and translucent. After reflux treatment, CEREC restorations rebuild the edges.
Choosing a dentist in Oakville for erosion
Look for a clinic that takes a full health history, looks for causes, and offers both prevention and restoration. Your dentist should be registered with the Royal College of Dental Surgeons of Ontario (RCDSO).

Frequently asked questions
Can acid reflux cause tooth sensitivity?
Yes. Reflux acid softens and wears away enamel, exposing the dentin underneath, which makes teeth sensitive to cold, heat and sweets.
Should I brush my teeth after acid reflux?
Wait about 30 to 60 minutes. Rinse with water first, since brushing softened enamel right away can wear it faster.
Can dental erosion from reflux be reversed?
Lost enamel can’t grow back. Early softening can be partly remineralized, and damaged teeth can be protected with bonding, veneers, onlays or crowns.
Which teeth does reflux damage most?
Reflux often wears the tongue side of the upper teeth and the chewing surfaces of the back teeth first.
Can a dentist tell if I have acid reflux?
A dentist can often spot erosion patterns that suggest reflux. Diagnosis and treatment of reflux itself are handled by your physician.
Conclusion
Frequent acid reflux can wear away enamel, causing sensitivity, yellowing and chipped teeth.
Treating the reflux, protecting enamel and restoring worn teeth early keeps the damage from growing.
