How many can not eat after filling a tooth? What materials are used today to treat caries? If you want to know the answers to these questions, you need to read this article.

"Two hours not to drink and not eat!" - most dentists have not used this phrase for a long time. With the advent of modern filling materials, dentists do not have to torture themselves, looking at their watches and refraining from eating. However, some municipal hospitals still have dental "relics", the use of which has such limitations.

How many can not eat after filling a tooth? Dental fillings: types of materials

Dental fillings are made of different materials. The time of their solidification depends on what substance the doctor used. If you forgot to learn from the dentist or he did not recommend anything to you, after reading this article, you will guess which set you used.

In the last century, the question of how much you can not eat after tooth filling, was very relevant. During the treatment of caries, various cements were used. Their quality was disgusting: if the doctor incorrectly kneaded the solution, the seal under the influence of saliva melted in the mouth of the patient, like ice cream on a hot day. Such seals could stand a maximum of 2-3 years.

Today, cement raw materials are used in dentistry because of their low cost. But, having decided to save, you need to take into account that it is not able to prevent the development of relapse, so you need to be ready for a re-treatment. In addition, cement fillings can quickly crack and fall out. And they harden very long.

Working with this substance, the dentist always warns the client, through how much you can eat after filling the tooth. From drinks and food it is better to refrain after visiting the doctor for 3 hours.

Glass-ionomers are one of the types of cement fillings. They have no shortcomings, described above, and they are considered ultramodern materials. The main advantage of glass-ionomer cements is their safety for health. In addition, this raw material in its composition contains fluorine, which for a long time protects the tooth from the action of bacteria that cause caries. These materials can not be influenced by moisture, which greatly facilitates the work of the dentist when treating a tooth in a zone that is difficult to dry out, for example, in the subgingival.

Metal seals

For a long time in dentistry metal seals were used, which they called amalgam. They could be copper, gold and silver. Despite their reliability and strength, the demand for such seals has disappeared as soon as alternatives have appeared. The amalgam was unaesthetic, solidified for a long time, it contained mercury. Patients with this material were treated with teeth, complained of metallic taste in the mouth and allergic reactions. In addition, work with him required special equipment.

Seals plastic

And how much you can not eat after tooth filling if plastic material was used? The appearance of this raw material has led to an agiotage. Such seals quickly gained popularity, but, as it turned out, they were toxic. Plastic was dyed under the influence of food and drinks and quickly lost shape.

In 90% of cases, patients developed periodontitis or pulpitis, very often an allergy to raw materials. If the plastic was installed crown, under it the tooth was destroyed very quickly. When this deficiency was detected, the substance was no longer used, and patients began to replace the seals previously established. That is why the question of the time of taking food after treatment with this raw material is no longer relevant.

Light seals

Light curing, photopolymeric or light dental fillings are a material radically different from the above. Its main feature is that it freezes under the influence of a special lamp. In the photopolymer mixture is heliocomposite. Under the influence of ultraviolet rays, it breaks down into radicals, which stimulate the process of solidification of the filling. In private clinics, dentists work with this raw material.

Before you figure out how much you can eat after tooth filling, you need to figure out what is good about this material. This polymer can not harden in the air, so the dentist can for a long time form the crown of the restored tooth. Photopolymers are plastic, they are perfectly amenable to polishing. Due to these properties and the abundance of shades of raw materials, a doctor can obtain a high aesthetic of restoration.

A light seal on the chewing tooth is placed only because it has high strength. It is also used for the "smile zone", as it has excellent aesthetic characteristics.

The question of how much you can not eat after tooth filling, it is logical, because no one wants to undergo stress and visit the dentist again in case of damage to the material. We want to calm you down. Light polimers on the teeth are kept long and reliably thanks to adhesives, which are applied to the tooth walls before treatment. A special glutinous system does not allow prematurely filling out the seal: it holds it firmly in the dental cavity. In addition, a chemical bond appears between the photopolymer seal and the tooth tissues.

Light polimers allow restoring the teeth in such precedents, in which earlier no seal could have been preserved, for example, with small notches, chips. The average life of this raw material is 5 years.

The photopolymer instantly hardens after exposing its surface with a heliolamp, therefore, as soon as the treatment is completed, the patient is allowed to have lunch or dinner.


Although after the treatment of teeth with a photopolymer there are no certain restrictions on the time of eating, some doctors forbid patients to eat. This refers to the circumstances in which a light seal has to be placed on the front teeth. If the surface of the frozen photopolymer is poorly polished, it can change its color. This will be facilitated by the use of beverages and products that color enamel: beets, coffee, chocolate, strong tea, tomatoes. The doctor may advise you to exclude such food from the diet in the next seven days to prevent the coloration of the seal. Dentists say that you need to follow the same "white diet" after the office bleaching so that the result is preserved as long as possible.

Do I need to eat before going to the dentist? Dentists advise their patients to come to the reception with full meals. After eating, the activity of the salivary glands is reduced, which greatly simplifies the work of the doctor. In addition, hungry people are more difficult to tolerate stressful situations.

If anesthesia was used during the treatment of the tooth, it is necessary to wait until the anesthetic has completed and only then can you eat. Otherwise, it is possible to damage the mucous membrane unintentionally when chewing food. This rule applies regardless of whether the photopolymer or any other raw material has been used.

Sometimes in the process of restoration of the tooth, the doctor puts a temporary seal, under which the medicine is placed. It freezes a long time, so after treatment for food it is worth abstaining for two hours.
