What's fluoride therapy?
Fluoride is a beneficial mineral that strengthens teeth and bones, especially during growth. Fluoride protects teeth from decay and promotes the health of tooth enamel. This substance not only stops the initial caries of the teeth, but also makes them resistant to the subsequent caries.
Research shows that fluoridated drinking water reduces tooth decay by up to 25%. For this reason, in some countries, some fluoride is added to drinking water.
Fluoride delivery methods to teeth
There are many topical methods for delivering fluoride to the teeth, which we will discuss below:
Fluoride toothpaste
The most common and important method is to use fluoride toothpaste. These toothpastes contain 1000 units of fluoride and are very effective when used consistently. Fluoride unit numbers for toothpaste are usually listed on the packaging.
Mouthwash containing fluoride
There are also fluoride mouthwashes, which have different fluoride concentrations. There are two types of mouthwashes daily and weekly. The daily type of fluoride has a lower concentration than the weekly type.
Fluoride supplement tablets
Fluoride supplements are usually prescribed for children ages 6 to 16 who do not have access to fluoridated drinking water. These supplements are available in pill or liquid form and are prescribed according to the age of the person.
Fluoride therapy
There is another method called fluoride therapy, which is easily done in dental centers. In this method, a large amount of fluoride is placed directly on the teeth, to kill germs and plaque and strengthen the structure of tooth enamel.
What is fluoride therapy?
Fluoride therapy means the topical application of fluoride to the teeth periodically to increase their resistance to decay. In this method, the dentist first cleans the teeth with a special brush and paste and then puts the fluoride that is in the form of gel or varnish on the dental tray on the teeth. Approximately one minute later, the person should empty the contents of their mouth as much as possible through the drainage tube, but the mouth should not be rinsed.
Fluoride therapy in children
This method is also used to prevent tooth decay in children. Fluoride gel has been used extensively in the past, but it was necessary for the child to sit still for 4 minutes and hold the fluoride container in his mouth. This is difficult for the child and he may swallow some of it.
Cost and price of fluoride therapy
Fluoride therapy costs less than most dental treatments to treat dental caries such as fillings and the like.
Pre-fluoride therapy training
Children should be well-nourished and drink plenty of fluids before fluoride therapy varnish, as it is not possible to eat or drink for up to an hour after fluoride therapy. Before applying fluoride varnish, it is better to clean the teeth with prophylactic paste (in the office) or regular brushing and remove any visible plaque or plaque. (Of course, prophylaxis is not necessary in case of lack of access to facilities).
Post-fluoride therapy training
To dry fluoride varnish, it is necessary to wait before discharging the patient because the varnish hardens in contact with oral fluids. The child should use a soft diet until the end of the day of fluoride therapy and should avoid eating solid foods. Until the next morning, the child should not use toothbrushes and floss. Discoloration of the tooth surface is normal after fluoride therapy and gradually returns to its original state after a while. For this purpose, it is recommended to drink a glass of milk one hour after fluoride therapy.
After fluoride therapy, the child feels a coating on their teeth. This coating has a dark mustard color. Thus, it is recommended that the child does not brush or floss his teeth for 4 to 6 hours after treatment, for the best possible result.
Side effects of fluoride use
Tooth discoloration or fluorosis
The most common complication of excessive fluoride consumption is tooth discoloration or fluorosis. Fluorosis is a condition in which white streaks or discoloration appear on the teeth. Fluorosis occurs when a child has consumed too much fluoride from birth to the age of eight (when teeth were growing under the gums). This condition can cause the teeth to turn white and brown or have distinct spots on the enamel or tooth surface. However, once the tooth development process is complete, the person will no longer have fluorosis.
Tooth discoloration is more common in children who have eaten too much toothpaste, or taken too much fluoride supplements. Therefore, fluoride toothpaste should not be used for children who can not get toothpaste out of their mouth.
Allergies
Some people may experience skin irritation from fluoride therapy, which is very rare.
Toxic properties
Fluoride, like any other substance, can be toxic if taken in large doses. This is not uncommon, however, fluoride varnish is recommended for children under 6 years of age.
