How to Fix Sensitive Teeth: Say Goodbye to Toothache

If people feel discomfort while brushing and flossing or when eating, it is most likely that they have sensitive teeth. Sensitive teeth can inhibit people from doing activities such as these, so it is important for people to be aware of what actually causes sensitive teeth and how to fix them. How to fix sensitive teeth?

What are the Causes of Sensitive Teeth?

Sensitive teeth are usually caused by exposed tooth roots and damaged enamel. Enamel is the top portion of a tooth above the gum line and this serves as a protective layer to the teeth. There are also other factors that add up to the cause of sensitive teeth such as the following:


These are damages located on the hard surface of the teeth and will actually worsen the condition of the teeth if it is not treated right away. This is because cavities increase in size when left untreated for too long.

Brushing too hard

Brushing the teeth too hard is also a cause of sensitive teeth. The reason why it is not a good idea to harshly brush the teeth is that this gradually takes away the enamel on the teeth. In addition, wrong technique and very hard toothbrush bristles may also cause this.

Dental erosion

This happens when people ingest acidic drinks and food. These actually melt away the enamel on the teeth and expose everything beneath the enamel and that is where teeth sensitivity comes from.

Acids from the stomach after throwing up due to bulimia or GERD also lead to dental erosion. When it comes to how to fix sensitive teeth, it is worthwhile to address other underlying medical issues.

Tooth grinding

When people clench or grind their teeth, this actually damages the enamel and wears it out. Eventually, it would lead to teeth sensitivity.

Cracked teeth and worn-out fillings

These are also causes of teeth sensitivity due to the crack on the surface of a tooth or teeth that reach down to the root and sometimes the gum line. When hot and cold temperatures come in contact with cracked teeth, that makes a person experience sharp pain.

Receding gums

The receding of the gums happens naturally due to age and when it does, it exposes the roots of the teeth. Since these do not have any protective layer, it will be a cause of tooth sensitivity.

Gum disease

Gum disease is caused by tartar or plaque build-up and when it is not treated right away it will wear out the bony support of the teeth and eventually, the teeth will develop pockets around the teeth and cause teeth sensitivity.

Teeth Whitening

People who undergo the bleaching of their teeth may feel temporary pain and teeth sensitivity. When it comes to how to fix sensitive teeth, you may want to seek other gentler means of lightening your smile.

How to Fix Sensitive Teeth?

When it comes to the question about “how to fix sensitive teeth?”, there are two options that people may choose from. First, they can consult their dentist and have their teeth checked or they can also opt for home remedies to alleviate the pain and fix sensitive teeth.

Dentist Consultation

  • The dentist will examine the patient’s teeth and identify the cause of teeth sensitivity.
  • The dentist will then recommend some products for the patient in order to ease their sensitive teeth. Products such as fluoride toothpaste or desensitizing toothpaste.
  • If the dentist sees that the cause of teeth sensitivity is severe, then they will perform the necessary procedures to fix sensitive teeth.
  • The dentist will apply fluoride gel onto the patient’s teeth in order to strengthen the tooth enamel which in turn, helps in alleviating sensations on the teeth.
  • The dentist may also do dental crown or dental bonding procedure in order to fix any damages done to the teeth.
  • The dentists may also perform a surgical gum craft if the patient is showing signs of gum loss from the root. This surgery is done by having a portion of gum tissue taken from the other parts of the mouth and applied to the affected area.
  • For more severe cases, a root canal will be done. This happens when all the other procedures mentioned above no longer work for the patient.

Home Remedies for Sensitive Teeth

When it comes to how to fix sensitive teeth and the proper treatments, it is recommended for people to consult their dentist in order to find out which brand and type of toothpaste they must use. Usually, fluoride toothpaste is recommended to fix sensitive teeth that are mild. Dentists recommend people apply this type of toothpaste twice a day when performing their regular dental hygiene.

How to Prevent Sensitive Teeth?

How to fix sensitive teeth? While there are available options for treatment, prevention is often a better route. Here’s what you can do.

  • Always see to it that oral hygiene is regularly practiced. People must brush their teeth at least twice a day and it is recommended to use fluoride toothpaste which is specifically made for sensitive teeth. Refrain from brushing the teeth vigorously and avoid brushing the teeth from side to side. Instead, do gentle and small circular motions.
  • Avoid consuming too many acidic and sugary foods.
  • A toothbrush must be changed regularly after two to three months.
  • If a person has intentions of having their teeth bleached, it is advised that they consult their dentist before the bleaching procedure in order to prepare them for the teeth sensitivity that is to come.
  • The teeth must not be brushed as soon as a person finishes their meal. Some particular foods soften the enamel of the teeth so it is best to leave it as is for at least an hour.
  • Some people unknowingly grind their teeth, especially at night. Dentists will advise these people to wear a mouthguard to prevent that from happening.
  • Always have regular trips to the dentist.
