Why does tooth sensitivity occur after tartar cleaning?

Causes of enamel hyperesthesia

Many patients complain of increased sensitivity of teeth after tartar removal. The main reason for such complaints is the exposure of hard tooth tissues that were previously covered with tartar. The deposits partially reduced the impact of irritants - high and low temperatures, sour, sweet and spicy foods. Therefore, after the stone is removed, the enamel reacts more sharply to external factors.

Increased tooth sensitivity is caused by:

• existing diseases of the oral cavity - caries, pulpitis,
• thinning of tooth enamel in the cervical area,
• non-compliance with professional cleaning rules.

To reduce the likelihood of enamel hyperesthesia, have your teeth cleaned only by qualified dentists. Contact only experienced specialists in whose professionalism you are confident.

Problems of dental hypersensitivity during professional oral hygiene

Unfortunately, modern personal hygiene products for the care of teeth with increased sensitivity provide a short-term effect. And some time after treatment, the patient again shows signs of hyperesthesia. Filling is carried out only if there is a defect in hard tissues. Tooth depulpation is resorted to when all of the above methods of eliminating hypersensitivity are ineffective.

Therefore, professional products such as fluoride-containing gels and varnishes have become widespread for the prevention and treatment of dental hypersensitivity. Gels typically contain low concentrations of fluoride and are recommended for weekly home use for persons over 18 years of age [3].

Unlike gels, fluoride-containing varnishes can remain on the tooth surface for a long time, thus promoting the accumulation of more fluoride in the enamel [2]. This is especially important at a time when demineralization processes predominate. However, when applying conventional fluoride varnishes, calcium fluoride crystals are freely located on the surface and are quickly removed by mechanical abrasion, making the effect short-lived. Therefore, preference should be given to drugs with a longer effect [7].

In our practice, for many years, we have successfully used fluoride-containing products such as VOCO Profluoride Varnish and Bifluoride 12 (VOCO, Germany). Prevention and treatment of hyperesthesia with the help of these drugs are based on closing the mouths of the dentinal tubules with calcium fluoride plugs, which, in turn, block the movement of fluid through them. This leads to a reduction and, ultimately, elimination of the occurrence of unpleasant sensations when exposed to thermal, chemical or tactile stimuli on the teeth.

"VOCO Profluoride Varnish»

is a fluorine-containing varnish based on a special resin (colophonium) containing 5% sodium fluoride. Fluoride ions, together with calcium ions present in the tubules, promote the precipitation of calcium fluoride, which leads to reliable sealing of the dentinal tubules. Along with this, VOCO Profluoride Varnish forms a depot of calcium fluoride on the tooth surface, which protects the tooth from acid attacks, promotes remineralization and the formation of fluorapatite. In addition, xylitol, which has a caryostatic effect, is added to the varnish. Colonium resin provides good adhesion, also on wet surfaces. Therefore, unlike other fluoride-containing preparations, VOCO Profluoride Varnish can be used successfully when it is impossible to dry the surface of the teeth well.

“Bifluoride 12” is a unique transparent fluoride varnish, which is a colorless suspension based on natural tree resin with a pleasant fruity smell and taste. I would like to note that all fluoride varnishes present on the dental market have an active ingredient of sodium fluoride, which has a short-term effect - 2-3 days. The main active components of Bifluoride 12, in contrast, are 6% sodium fluoride and 6% calcium fluoride. It is the presence of calcium fluoride that contributes to better penetrating ability of the drug and provides a long-term therapeutic effect - the release of fluoride occurs over several months.

It is obvious that conventional fluoride varnishes, which are natural resins, do not form a very strong film on the surface of hard tooth tissues, and calcium fluoride crystals are freely located on the surface and are quickly removed by mechanical abrasion, making the effect short-lived [6].

The composition of “Bifluoride 12” includes bioinert Teflon particles, which give it strength properties, and the submicroscopic CaF2 crystals formed during its application are not located on the surface, but directly in the pores of the loosened zone of enamel, dentinal tubules and in the cement of the tooth root. Bifluoride 12 dries quickly, so to obtain long-term adhesion to the enamel it should be applied in a thin layer. To maintain the anti-caries effect, re-coating must be carried out after 3-6 months. Single-layer application of varnish saves the doctor’s time and reduces consumption to a minimum, on average 66% more economical than analogues.

It is important that the problem of dentin sensitivity has led to the creation of a new class of complex drugs aimed at eliminating it: these are dental desensitizers, for example, Admira Protect (VOCO, Germany).

Desensitizers reduce hypersensitivity by sealing the dentinal tubules, that is, they have a “plug-forming” effect [1, 4].

Admira Protect includes several components balanced to achieve maximum desensitizing effect: HEMA (hydroxymethyl methacrylate) and aminofluoride. HEMA acts as a wetting agent, creating the necessary moisture in dentin and preventing the collapse of collagen fibers. This allows the surface layers to be easily impregnated with the main component, developed using a special organic matrix filling technology to thoroughly seal the dentin. Active fluorides help strengthen the structure of hard dental tissues, as they are able to penetrate them and obstruct dentinal tubules, reducing the sensitivity of dentin [2].

Since Admira Protect is a synthetic varnish, it forms a more durable film on the tooth surface compared to preparations based on natural and natural-synthetic resins. It is enough to apply the drug once every 6 months.

Here is a clinical example.

1. Patient A., 62 years old, came to the therapeutic dentistry clinic for the purpose of sanitation of the oral cavity. Before the start of sanitation, the patient was recommended to carry out professional hygiene (Fig. 1, 2). Removal of dental plaque was carried out using an ultrasonic device of the piezoelectric type “P Max”, Satelec (Fig. 3); polishing the tooth surface - using an air-abrasive tip “Air-Flow Handy 2”, EMS (Fig. 4). To prevent the occurrence of hypersensitivity in the patient, taking into account slight bleeding of the gums after professional cleaning, Bifluoride 12 applications were used (Fig. 5). After 1 application, her symptoms of dental hypersensitivity disappeared.

Thus, the use of professional products that reduce tooth sensitivity and seal dentinal tubules is one of the most effective, reliable and fastest ways to eliminate dentin hypersensitivity, both when used independently and in complex treatment of this pathology.

Complex of symptoms

Increased sensitivity of teeth after cleaning from tartar can manifest itself in different ways. Most often, patients feel:

• discomfort when chewing food and brushing teeth,
• aching pain of varying degrees of intensity when leaving a warm room into the cold, eating hot and cold foods and drinks.

Normally, this condition can persist for 2-7 days. If enamel hyperesthesia does not go away or worsens over time, do not delay your visit to the dentist.

Why do dental deposits form?

• The abundance of phosphates in saliva due to metabolic disorders.
• Irregular cleaning of the oral cavity, lack of knowledge of proper hygiene, lack of attention to the interdental space.
• Low-quality hygiene products: toothpastes, rinses and brushes from unscrupulous manufacturers who only promise a therapeutic effect.
• Poor heredity is a genetic predisposition to the formation of dental plaque.
• Excessive amount of soft food in your menu. During active chewing, natural plaque removal occurs.
• Dietary and other habits: regular consumption of tea and coffee drinks, smoking leads to darkening of the enamel and the deposition of sediment on the surface of the tooth.

Treatment and prevention measures

To reduce the risk of developing hyperesthesia, fluoridation is carried out after professional hygiene with the removal of tartar. Procedure:

• saturates the enamel with useful substances that help strengthen it and restore its structure,
• reduces the likelihood of developing caries.

To avoid enamel hypersensitivity after removing tartar, you must follow the following rules:

• do not eat or drink for two hours after the procedure,
• give up solid and rough foods for a day,
• use a toothbrush with soft bristles,
• Use mouth rinses regularly.

To maintain healthy teeth and gums, professional hygiene with the removal of soft bacterial plaque and tartar should be carried out twice a year.

Rehabilitation after cleaning

To prevent gum inflammation from starting after professional teeth cleaning, the patient should be attentive to himself and follow all the doctor’s recommendations regarding rehabilitation. Correct behavior and oral care will allow you to consolidate the results of cleaning for a long time, eliminate inflammation and prevent its complications.

Tartar formation

There are two ways to accumulate solid plaque, depending on the location of its accumulation:

1. Above the gums. Formed as a result of the activity of pathogenic organisms. It is easy to notice when a person smiles. The edges of the teeth appear darker or have a yellow tint. Often it is localized on the inside. In this case, it is more difficult to detect the problem.
2. Under the gums. At first glance, the teeth look healthy. But if you pay attention to the mucous membrane, it appears bluish. Swelling and bleeding may occur. A stone located between the gum and the root of the tooth can lead to the formation of local suppuration.

Typically, such dental deposits are noticed by a specialist during a routine examination. Only an experienced dental hygienist can detect and eliminate this problem.
