Causes of sensitive teeth


A large part of society is affected by hypersensitive teeth (dentine hypersensitivity). The pain occurs mainly when consuming cold and hot drinks as well as sugary and salty foods.

The cause of the pain is due to a change around the dentin, the most important part of a tooth. There is a cavity inside the tooth. Nerve fibers and blood vessels run there. The tooth neck and enamel serve as a protective layer for our teeth. Since receding gums and tooth neck is exposed, the tooth is sensitive to external stimuli and the sensation of pain begins. There can be various causes for this receding gum.

Sensitive teeth due to the wrong brushing technique: Teeth that are sensitive to pain are often the result of an incorrect brushing technique.

If you brush your teeth with too much pressure, the enamel will be removed and the necessary protective layer will be damaged. Be careful not to “scrub” with excessive pressure to preserve your dental health.

Sensitive teeth from dental diseases


Dental diseases such as periodontitis or deep gum inflammation are often the cause of pain sensitive teeth. Poor oral hygiene and the resulting accumulation of bacteria cause your entire teeth to become inflamed, which leads to teeth that are sensitive to pain. Untreated dental diseases cause the gums to recede and thereby expose our sensitive tooth necks.

At the first signs of toothache, you should see your dentist in order to be able to identify and treat dental diseases early on.

5 tips: How to prevent sensitive teeth

Use the right toothbrush

Be sure to use a toothbrush with soft or medium-hard bristles. Toothbrushes with hard bristles attack your gums and tooth enamel. Special sonic toothbrushes have built in a pressure control and alert you as soon as you exert too much pressure when brushing your teeth.

Our tip: Change your toothbrush regularly, as a lot of bacteria accumulate on the bristles, which can cause dental diseases.

Find the right toothpaste

It makes sense to use a special toothpaste for sensitive teeth. These “sensitive” toothpastes contain fluoride and other active ingredients for desensitization. The ingredients help counteract the sensitivity of your teeth to pain by coating the tooth necks and strengthening the natural protective layer.

Our tip: If you have sensitive teeth, you should avoid whitening toothpastes, as the abrasives they contain also attack and damage your teeth.

Use a mouthwash for sensitive teeth

There are special mouthwashes that are tailored to the needs of sensitive teeth and gently remove bacteria.

Our tip: Make sure that the mouthwash does not contain alcohol. This also causes unpleasant pain in the mouth.

Brush with gels that contain fluoride

Another way to relieve hypersensitivity of your teeth is to use fluoride gels. It is applied once a week and helps harden tooth enamel and protect exposed tooth necks. Your dentist will help you find the right products for your dental care.

Ask about a fluoride treatment

If your teeth are very sensitive to pain, your dentist has the option of having your tooth necks sealed with a varnish. A special fluoride-containing varnish is used, which closes the exposed tooth necks and covers them with plastic. This treatment reduces the sensation of pain and protects your teeth from dental diseases.
