Coffee acidity, caffeine gum and your teeth

Acidity, staining, saliva and sugarfree gum

Coffee is mildly acidic, and the longer it sits in your mouth the longer your enamel spends below the point where it starts to soften — slow sipping is worse than a quick cup. Sugarfree gum works the other way: chewing stimulates saliva, and saliva is what neutralises acid and carries the minerals enamel repairs itself with. Neither fact makes gum a substitute for brushing.

Does coffee make your mouth acidic?

Yes. Black coffee is mildly acidic, and every sip lowers the pH in your mouth. Tooth enamel starts to soften once the mouth drops below about pH 5.5, and it is saliva that slowly brings it back up to neutral. The problem is not one cup but how long it lingers: each sip starts that recovery over again.

Why is sipping coffee slowly bad for your teeth?

Because for enamel, how often your mouth turns acidic matters more than how much you drink. A cup finished in ten minutes gives saliva one acid episode to clear. The same cup sipped across an hour keeps topping the acid up, so your mouth spends most of that hour below neutral instead of recovering.

Does caffeine gum make your mouth acidic?

Chewing sugarfree gum works the opposite way to sipping coffee. Chewing makes you produce more saliva, and saliva is the mouth's own buffer: it carries bicarbonate, which pulls the pH back toward neutral. That is why dentists suggest sugarfree gum after eating or drinking. Kaffgum is sugarfree, so there is no sugar for mouth bacteria to turn into acid. We have not yet had the final formula tested for its effect on mouth pH, so we will not quote a number.

Is caffeine gum better for your teeth than coffee?

On acidity and staining, the format has the advantage. There is no cup of acidic, dark liquid washing over your teeth for as long as you drink it, and the chewing raises saliva flow, which helps your mouth return to neutral. Two limits: it only holds for sugarfree gum, and neither replaces brushing twice a day.

Is chewing gum bad for my teeth?

Sugarfree gum is not. Kaffgum has zero grams of sugar, and chewing stimulates saliva, which helps neutralise acid. It is not a substitute for brushing.

How do I prevent dental problems from drinking coffee?

Three things help most: drink it in one sitting rather than sipping for an hour, rinse with water afterwards, and wait about thirty minutes before brushing so you are not scrubbing acid-softened enamel. Swapping some of your coffee for sugarfree caffeinated gum also helps — chewing sugarfree gum stimulates saliva, which is what neutralises acid and clears staining compounds, so you get the caffeine without another acidic drink sitting on your teeth.

Does coffee stain your teeth?

Yes. Coffee contains tannins, which help pigment bind to enamel, and it is acidic enough to soften the surface that pigment binds to. Frequent sipping is worse than drinking it quickly. Sugarfree gum after a cup increases saliva flow, which helps clear both the acid and the pigment.

Is sugarfree gum good for your teeth?

It is generally considered helpful rather than harmful. Chewing stimulates saliva, and saliva is what neutralises acid, clears food debris and carries the minerals enamel repairs itself with. It is not a substitute for brushing, and the benefit depends on the gum being sugarfree — Kaffgum has zero grams of sugar.

Does caffeine gum freshen your breath?

Mint does the job properly, and both flavours benefit from being sugarfree and from the saliva chewing produces. It is the rare caffeine format that improves your breath rather than ruining it.

Can I chew caffeine gum with braces?

Ask your orthodontist. Advice on gum and braces varies with the appliance and the practitioner, and that is a conversation with the person who fitted them rather than something to settle from a product page.

Can chewing gum cause jaw pain?

Chewing anything for long enough can aggravate the jaw joint, particularly if you have TMJ problems. You only need a few minutes per piece to release what it is carrying, so there is no reason to chew one for an hour. If your jaw aches, you are chewing too long.
