can electric toothbrushes cause mouth ulcers

If you’re like me, you’re always looking for ways to improve your oral hygiene. I’ve tried all sorts of different toothbrushes, from manual to electric, and I thought I’d give the latter a try. Little did I know that electric toothbrushes can actually cause mouth ulcers!


An electric toothbrush is a toothbrush that uses an oscillating motor to rotate bristles on the brush head. The rotation speeds of the brush head can range from about 300 times per minute to about 1,200 times per minute. Some electric toothbrushes also have vibration features.

What are mouth ulcers?

A mouth ulcer is an open sore in the mouth. Mouth ulcers are usually painful and can make eating and talking uncomfortable. They usually go away in a week or two.

Mouth ulcers are common, affecting around one in five people in the UK at any one time. They’re more common in women than men, and most people will have them at some point in their lives.

There are different types of mouth ulcer, but the most common is called an aphthous ulcer. These usually start as a small red spot, before developing into a white or yellowish patch with a red border. Aphthous ulcers tend to be round or oval and can vary in size from about 2mm to 8mm across.

What causes mouth ulcers?

Mouth ulcers are small, painful sores that occur inside the mouth. They can be caused by a number of things, including infection, injury, acid imbalances, and certain medical conditions.

Infection is one of the most common causes of mouth ulcers. The bacteria that cause plaque buildup on teeth can also cause mouth ulcers. Infections can also be caused by viruses, such as the herpes simplex virus (HSV), which is responsible for cold sores. Injury to the mouth can also cause ulcers to form. This can happen from biting your cheek or tongue, wearing ill-fitting dentures, or after dental surgery.

Acid imbalances in the mouth can also cause ulcers to form. This is most commonly seen in people with gastroesophageal reflux disease (GERD), in which stomach acid backs up into the throat and mouth. Certain medical conditions, such as Crohn’s disease, celiac disease, and Behcet’s disease, can also cause mouth ulcers.

Can electric toothbrushes cause mouth ulcers?

electric toothbrush might be the reason you have a mouth ulcer. Several factors can contribute to developing mouth ulcers, including brushing your teeth too hard, hormonal changes, food allergies, and viral infections. If you’ve noticed that you tend to get mouth ulcers after using an electric toothbrush, it’s important to figure out whether the toothbrush itself is causing the problem or if some other factor is at play.

It’s also worth noting that mouth ulcers are relatively common — as many as 20 percent of people experience them at some point in their lives. So, if you get a mouth ulcer after using an electric toothbrush, it’s not necessarily cause for alarm. However, if you find that you’re getting mouth ulcers more frequently or that they’re particularly painful, it’s worth talking to your doctor or dentist to rule out any underlying medical conditions.

How to prevent mouth ulcers?

Toothbrush abrasion is one possible cause of mouth ulcers. Abrasion occurs when the bristles of your toothbrush wear away at your gum tissue. This can happen if you brush too hard or if you use a toothbrush with bristles that are too stiff. To prevent this from happening, use a soft-bristled toothbrush and brush gently.

Mouthwashes and other oral hygiene products can also cause mouth ulcers in some people. If you think this might be the case for you, try using a different product or diluting the product you’re using before applying it to your gums.

If you regularly get mouth ulcers, talk to your dentist or doctor. They can help you determine the underlying cause and recommend the best treatment for you.

Treatment for mouth ulcers

Mouth ulcers are open sores that can occur inside the mouth, on the gums, or on the lips. They can cause pain, redness, and swelling. Electric toothbrushes are often used to help treat mouth ulcers.

There is no definitive answer on whether or not electric toothbrushes can cause mouth ulcers. Some people may be more susceptible to developing mouth ulcers when using an electric toothbrush, while others may not experience any issues. If you are concerned that your electric toothbrush may be causing mouth ulcers, try using a different type of toothbrush and see if your symptoms improve.
