If you deal with frequent heartburn, that sour taste in the back of your throat, or a diagnosis of GERD (gastroesophageal reflux disease), you already know it can be uncomfortable. What many people do not realize is that stomach acid making its way up into the mouth can also quietly wear away tooth enamel, often with no pain at all until the damage is noticeable. Here is what is happening, what to watch for, and how we can help protect your smile.
How Stomach Acid Reaches Your Teeth
Your stomach produces acid strong enough to break down food, and that same acid can dissolve tooth enamel on contact. When reflux sends acid up into the mouth, whether as noticeable heartburn or silent reflux you do not feel, it lowers the pH around your teeth. Enamel begins to soften and dissolve at a pH below about 5.5, and stomach acid is far more acidic than that. Unlike cavities, which are caused by bacteria feeding on sugar, this kind of damage, called dental erosion, comes from direct chemical contact with acid. Frequent nighttime reflux is especially damaging, since saliva flow, which normally helps neutralize acid, slows dramatically during sleep.
Warning Signs of Acid Erosion
Erosion tends to develop gradually, so early signs are easy to miss. Watch for:
- Increased sensitivity to hot, cold, or sweet foods and drinks
- Teeth that look more yellow as enamel thins and the darker dentin underneath shows through
- Smooth, glassy-looking tooth surfaces, especially on the back (tongue-side) of upper front teeth
- Rounded or cupped-out chewing surfaces on molars
- Edges that look thin, translucent, or chip easily
- A sour or acidic taste, or a burning sensation, after reflux episodes
Because erosion often affects the back surfaces of the upper front teeth first, it is easy to miss without a dental exam, which is one reason regular preventative care visits matter even when nothing seems wrong.
Who Is Most at Risk
Erosion tends to be worse in people with frequent or long-standing reflux, those with nighttime symptoms, and anyone with reduced saliva flow, since saliva helps buffer acid and wash it away. If you also deal with dry mouth, the combination can accelerate enamel loss. Frequent vomiting from other causes, certain eating patterns, and highly acidic diets can compound the effect of reflux on enamel.
Protecting Your Teeth While Managing Reflux
- Work with your physician to manage reflux itself. Better control of GERD reduces the acid exposure your teeth face.
- Do not brush immediately after a reflux episode or vomiting. Enamel is temporarily softened by acid, and brushing right away can wear it away faster. Rinse with plain water or a small amount of baking soda in water, and wait about 30 to 60 minutes before brushing.
- Chew sugar-free gum after episodes to stimulate saliva flow and help neutralize acid.
- Ask us about a stannous fluoride toothpaste or a prescription-strength fluoride, which can help strengthen enamel against acid attack.
- Avoid pairing reflux-triggering foods with additional acidic drinks like soda, citrus juice, or wine.
How We Can Help
At your regular visits, we check for the early, subtle patterns of erosion, especially on the surfaces most exposed to reflux, and we can often spot changes before you notice any symptoms yourself. If erosion is already present, treatment depends on how much enamel has been lost: for mild cases, fluoride varnish and a remineralizing toothpaste may be enough to protect the tooth, while more significant wear may call for bonding or crowns to restore the tooth’s shape and protect it from further damage. If you have not been formally diagnosed with GERD but we notice an erosion pattern consistent with reflux, we will let you know so you can follow up with your physician. For a deeper, evidence-based look at what the research shows, see our clinical review of GERD and dental erosion.
