Chewing Gum for Heartburn: Does It Work?

Short answer: Small studies suggest chewing sugar-free gum after a meal may help clear acid from the esophagus because it increases saliva, but the evidence is limited and the effect is modest. Avoid mint flavors, which NIDDK lists among common triggers. Gum does not treat the cause of reflux, and frequent heartburn still needs medical review. Last reviewed 20 Oct 2026.

Key takeaways

Chewing increases saliva, which helps wash acid down and buffer it.
In small studies, gum chewing reduced acid exposure after a meal; these were short, small studies.
Choose sugar-free gum and avoid mint flavors, which NIDDK lists among commonly linked foods.
Gum is not a substitute for medicines, meal timing or other habits.
Skip gum if it causes bloating, jaw pain or if you have dental or choking concerns.

How saliva helps with reflux

Saliva contains bicarbonate, which neutralizes some acid, and swallowing carries refluxed fluid back into the stomach. Chewing stimulates saliva flow and makes you swallow more often. That is the basis for the idea that gum might shorten the time acid sits in the esophagus. It is a reasonable physiological argument, which is why researchers tested it.

What studies show

The research is small and short. A study published in 1997 in healthy volunteers found that doubling saliva flow with gum shortened how long it took to clear acid from the esophagus. A 2005 study in the Journal of Dental Research looked at 31 people with reflux symptoms after a refluxing meal and found that gum chewing reduced the time the esophagus was exposed to acid compared with not chewing. A 2001 study in people with throat reflux found raised pH with gum chewing, more so with bicarbonate-containing gum.

These findings are consistent but small, and they measured acid exposure, not whether people lived with fewer symptoms over months. We did not find large trials, and no major guideline we read lists gum as a treatment. A fair summary is: it may help a little, it is cheap, and it is low risk for most people if you choose carefully.

Limits of the research

It is worth being clear about what the studies cannot tell us. Most were short, measured acid exposure on a single day, and involved small groups, some of them healthy volunteers rather than people with long-standing GERD. None followed people for months to see whether symptoms, medicine use or complications changed. Gum chewing also cannot be blinded convincingly, so people know whether they are chewing. That does not make the findings wrong, but it makes them early evidence. Think of gum as a harmless habit that may help a little, not as an established therapy.

The 2001 study in people with throat symptoms also suggests bicarbonate-containing gum raised pH more than ordinary gum. We would not seek out special products on the strength of that; discuss with a clinician if you are curious.

Which gum, and when

Sugar-free. Sugar-containing gum adds sugar, which is bad for teeth, and reflux already puts enamel at risk; see acid reflux and tooth erosion.
Avoid mint flavors if mint bothers you. NIDDK lists mint among foods commonly linked to GERD symptoms, and we cover why in peppermint tea and acid reflux. Fruit or cinnamon flavors may suit some people better, though cinnamon can bother others.
After eating. In the studies, people chewed after a meal, when acid exposure is highest. No guideline sets a standard duration, so we do not suggest a specific number of minutes.
Sweeteners. Sugar alcohols such as sorbitol can cause gas or loose stools in some people if you chew a lot.

Gum versus other saliva boosters

Some people ask whether sugar-free lozenges or sweets do the same thing. In principle, anything that stimulates saliva and swallowing might help, but the studies we found tested gum, so we cannot say the same for other products. Be careful with sour candies and fruit lozenges: they are acidic and often sugary, which is hard on teeth and may bother a sensitive throat. Peppermint lozenges bring the mint issue back. Sipping plain water after a meal can also help rinse the esophagus and the mouth, though it does not stimulate saliva in the same way.

If dry mouth is a regular problem, that is worth raising with a dentist or doctor, because some medicines cause it and it can affect teeth and reflux symptoms.

The book and pregnancy

We read the member copy of The Acid Reflux Strategy that the publisher gave us free for review. We did not buy it and have not followed it. We mention it only to say what it claims and to check that claim against public medical sources. It lists chewing gum among tips for pregnancy reflux, as a way of boosting saliva. That is in line with the small studies above, and it is a low-risk suggestion for most people. Pregnancy heartburn has its own considerations; see acid reflux during pregnancy and ask your midwife or doctor.

Who should skip it

People with jaw pain or temporomandibular disorders.
People who swallow a lot of air and get bloated or belch more when chewing.
Anyone with dentures, dental work or loose crowns that gum can pull on.
Young children, because of choking risk.
People who find that gum triggers symptoms; stop and note it.

Gum and your teeth

Reflux can erode tooth enamel, as we describe in acid reflux and tooth erosion. Sugar-free gum does not feed the bacteria that cause cavities and increases saliva, which helps buffer acid in the mouth, so it is generally considered tooth-friendly. Avoid brushing immediately after an acid episode, because softened enamel can wear faster; waiting some time before brushing is commonly advised, and your dentist can give personal advice. Sugar-containing gum does the opposite: it adds sugar to a mouth that may already be under acid attack.

What gum can’t do

Gum will not strengthen the valve, reduce stomach acid, or replace the habits and medicines that matter: smaller meals, finishing eating 3 to 4 hours before bed, avoiding triggers, not smoking, and a healthy weight (NHS, NIDDK). If you rely on gum every day for heartburn, that is a sign to see a doctor. See how to ease acid reflux fast and natural remedies for acid reflux.

Questions to ask your doctor or pharmacist

Would gum chewing be reasonable for me given my jaw, teeth and dental work?
Is my heartburn frequent enough to need evaluation?
Could my medicines contribute to reflux?
What can I do to protect my teeth from reflux?
Is gum chewing fine during pregnancy for my symptoms?

When to get medical care. See a doctor promptly if you have trouble or pain when swallowing, unexplained weight loss, loss of appetite, persistent vomiting, vomit that contains blood or looks like coffee grounds, stools that are black and tarry or contain blood, or chest pain (NIDDK, NHS). Call emergency services (911 in the US, 999 in the UK) for sudden chest pain, vomiting blood, or black, sticky or bloody stools. Chest pain can come from the heart, so do not assume it is reflux; see acid reflux and chest pain.

Medicines. Do not stop, skip or change any prescribed medicine, including a proton pump inhibitor (PPI), H2 blocker, blood thinner or blood-pressure drug, because of anything you read here. The NHS says not to stop a prescribed medicine without speaking to a doctor first. Ask your pharmacist about interactions before adding any herb, supplement or remedy.

FAQ

Does chewing gum help heartburn?

Small studies suggest it can reduce acid exposure after meals by boosting saliva, but evidence is limited and it does not treat the cause.

What kind of gum is best for acid reflux?

Sugar-free gum, avoiding mint flavors if mint bothers you, is a cautious choice.

How long should I chew gum after eating?

No guideline gives a standard time, so we do not suggest a number. Stop if you get jaw pain, gas or other symptoms.

Can gum make reflux worse?

It can if it is mint-flavored, if you swallow air, or if the sweeteners upset your stomach.

Is gum a substitute for reflux medicine?

No. Do not stop or change prescribed medicine because of gum; talk to your doctor.
