Urban legends about dental care

In this post we are going to dismantle certain popular myths and beliefs about dental care and treatment. Do not believe everything you hear!

A good rinse with a mouthwash replaces brushing

The best oral hygiene measure is brushing in all its possibilities, that is, also interdental, since the most important thing is the mechanical removal of dental plaque, inside which are the bacteria.

Mouthwashes contain antiseptic chemicals to kill bacteria but do not remove dental plaque, which is the reservoir and medium for bacterial growth.

Chewing gum is a good substitute for brushing

It is true that chewing gum is a generator of saliva and therefore increases its pH, which is why it can protect against the generation of caries, but it does not eliminate plaque or bacteria.

Therefore brushing remains the most important hygienic action.

Wisdom teeth must be extracted because they are useless and, in addition, they move the rest of the teeth

This is another widespread dental legend. Wisdom teeth do not move teeth. The teeth in many people come together towards the front of the mouth due to the effect of the muscular forces of the cheeks and tongue, together with the progressive loss of tooth support. Therefore the wisdom teeth are not to blame.

Wisdom teeth should only be removed if they cause repeated pain or are causing a problem in the previous tooth, the second molar, or tooth decay or a periodontal problem.

Also for needs for orthodontic treatment in which we need a certain space.

An infected tooth cannot be extracted

Generally speaking this is not true. The fact that there is an infection does not imply that it is impossible to perform an extraction, since the important thing is to eliminate the cause. In the same way that if someone has appendicitis, it is necessary to act by eliminating the appendix, this can be extrapolated to oral infections.

The only drawback is that the effect of the anesthesia is reduced and you probably have to put more quantity.

In patients with some heart diseases, it is better to eliminate the infection first, due to the consequences that bacterial endocarditis could produce.

After a root canal, I can’t feel pain

The nerve of a tooth is only a transmitter of thermal changes. It produces pain due to hypersensitivity and when it is affected by deep caries, it is what is called pulpitis.

If the tooth does not have a nerve, it can also hurt since the bone tissue, periodontal ligament that surrounds its roots can become inflamed and/or infected and cause pain, mainly when biting, but never related to thermal changes.

If I get my teeth cleaned, they will be whiter

No, the teeth will have the same color, only the stains will be removed. To have whiter teeth you have to do whitening, or place veneers to make them even whiter.

The natural color of the tooth will be maintained.

Halitosis comes from the stomach

Generally the causes of halitosis are from the mouth. One of the causes is the accumulation of food between the teeth and the non-removal of said remains.

Another cause is dry mouth. The reduction of saliva increases the bad smell. And finally the back of the tongue, which should be brushed to reduce this problem.
