Tooth Decay Treatment in Ukraine

Caries is the gradual destruction of the hard tissues of a tooth by acids produced by the microbial biofilm on its surface. The acid washes calcium and phosphates out of the enamel, saliva returns some of them, and as long as the two processes are in balance the tooth stays intact. The balance is upset by frequent snacking and sugary drinks, inadequate cleaning between the teeth, a dry mouth, and deep natural grooves on the chewing surface.

Caries develops in stages, and the treatment depends on the stage. At the white spot stage the enamel is still intact but has lost minerals, and a matt chalky area can be seen on it; no drill is needed here, and the process is halted by remineralisation. Superficial caries already has a cavity within the enamel. Moderate caries reaches the dentine, and that is when a brief reaction to sweet and cold appears. Deep caries comes right up to the pulp, leaving a thin layer of dentine over it. After that comes pulpitis, followed by apical periodontitis, and these call for a different approach.

Any defect that has been found needs treating, whether it bothers you or not. The main trap of caries is that pain appears late: enamel has no nerve endings, and between the teeth and under old fillings a lesion grows unnoticed for years. "It doesn't hurt" does not mean "there is no decay": early stages can be seen only at an examination under magnification and on an X-ray, so a preventive check-up every six months makes sense even when you have no complaints at all.

There are situations where a restoration is not the answer. With irreversible inflammation of the pulp or apical periodontitis, the canals are treated first; a tooth with almost no walls left above the gum is restored with a post and core and a crown, or extraction is discussed; with active gum inflammation and heavy plaque, treatment begins with a hygiene stage. Non-carious lesions are a separate group: enamel erosion, wedge-shaped defects, fluorosis. They look similar but have a different cause, and the treatment is different too, so the diagnosis is made after an examination, not from a photograph.

MediUkraine is a treatment search and coordination service, not a clinic. We find the clinic and a doctor with the right specialism, arrange the visit dates and support you throughout, including if you are travelling from abroad. The scope of the procedure and the approach are decided by the doctor after an in-person examination and X-rays.

Diagnosis begins with cleaning and drying the surface: an early spot cannot be seen on wet enamel. The tooth is examined under magnification and the density of the tissue is gently checked with a blunt probe; a sharp one is not used on a spot, because it can easily break through the still thin enamel over the lesion. Periapical and bitewing X-rays show what cannot be seen in the mouth: caries between the teeth, under old fillings and at the margins of crowns. Laser fluorescence and transillumination help in doubtful cases, but the decision is made on the overall picture, not on a reading from the device.

The white spot stage is treated without a drill. As long as the enamel is intact and there is no cavity, lost minerals can be restored: high-concentration fluoride varnishes and gels at the clinic, pastes with calcium and phosphates at home, a review of hygiene and of how often you snack. A check is scheduled after three to six months: the spot either stops and hardens or progresses further, and then the approach is changed. An intermediate option is resin infiltration: the porous area of enamel is etched and impregnated with a liquid resin that seals the micropores from within and halts the process without drilling; the method works for spots between the teeth and after braces, but only while there is no cavity. The condition for success is simple, if unwelcome: without a change in daily care remineralisation will not work, because the cause remains in place.

Once there is a cavity, preparation is needed, and the principle of minimal intervention applies: the affected tissue is removed and everything that can be preserved is kept. Twenty years ago cavities were still routinely enlarged "for safety"; this approach has been abandoned because every unnecessary millimetre of dentine ground away weakens the tooth permanently. Softened dentine is removed with a slow-speed bur, ultrasonic or air-abrasion tips, and caries detector dyes are used as a guide, bearing in mind that they also stain healthy demineralised dentine.

Deep caries is managed differently, and the goal here is to keep the pulp alive. Instead of cleaning the cavity down to a hard floor and exposing the nerve, selective removal is used: the tissue along the walls is removed completely, while a thin layer of altered dentine over the pulp is deliberately left and covered with a calcium silicate material. These materials are alkaline, suppress bacteria and stimulate the formation of reparative dentine, and a sealed restoration on top cuts the lesion off from its nutrition. If the pulp has nevertheless been exposed at a single point and the tooth had not caused trouble before, direct pulp capping is considered.

Whether a restoration can still help depends on the state of the pulp. Prolonged spontaneous pain, aching pain at night, a long reaction to heat that does not pass once the stimulus is removed are signs of irreversible inflammation, and root canal treatment is then needed. To be honest about the unwelcome part: sometimes the true depth of the lesion becomes visible only during preparation, and the plan changes right there in the chair. That is why the doctor discusses this scenario and its cost in advance, not after the tooth has already been opened.

Rubber dam isolation is the part of the protocol that patients often see as an unnecessary inconvenience. A thin sheet on a frame separates the tooth from saliva, the moisture of exhaled air, the tongue and the cheek. Adhesive systems are sensitive to moisture: a drop of saliva on etched enamel reduces the bond, and that is where a gap along the margin and secondary caries appear over the years. The rubber dam also stops small instruments and materials from getting into the airway and keeps the field dry throughout the visit. Talking with it in place is awkward; swallowing and breathing are unrestricted.

Next comes the adhesive protocol. Enamel is etched with phosphoric acid for about thirty seconds and dentine for roughly half that time; the acid is then rinsed off thoroughly, the dentine is dried to a moist sheen without over-drying, and an adhesive is applied and cured with a light. Self-etch systems reduce the number of steps. Getting the timings right matters as much as the brand of material: over-dried dentine causes post-operative sensitivity, while inadequate etching gives a weak bond.

Layered composite restoration is the main way to restore a tooth in a single visit. The material is placed in increments of about 2 mm and each is cured separately: composite shrinks by a few percent as it sets, and it is the layering that stops the shrinkage pulling the walls of the tooth with it. The shape is rebuilt according to the anatomy of the particular tooth: the cusps and fissures on the chewing surface, and a tight contact point with the neighbouring tooth using a matrix and a wedge. The shade is matched against a shade guide in daylight, and in the smile zone it is built from several masses of differing translucency.

The work is finished with a bite check and polishing. Articulating paper is used to find high spots: a restoration that is even fractions of a millimetre too high causes pain on biting and overloads the tooth. Polishing with discs, strips, rubber cups and pastes makes the surface smooth, and smooth composite holds less plaque and changes colour more slowly. This stage only looks cosmetic.

A direct restoration is not always suitable. When more than half of the crown of the tooth has been destroyed or a cusp has been lost, a ceramic inlay or onlay made in a dental laboratory is more reliable, and where a root-treated tooth is badly broken down, a crown. Baby teeth are managed according to their own protocols: glass ionomers and preformed paediatric crowns are used, and when full treatment is not possible, arrest therapy with silver diamine fluoride, which halts the process but leaves a dark stain.

Straight after the visit the tooth is fully functional: light-cured composite hardens under the lamp in the chair, so there is nothing to wait for. The only restriction is not to eat until the anaesthetic has worn off, usually one to two hours. Children are reminded of this separately: a numb lip or cheek is easy to bite without noticing.

Sensitivity to cold and to biting in the first days is an expected reaction, not a sign of a mistake. The tooth has just been through preparation and adhesive treatment, and the pulp needs time to settle. Sensitivity usually fades within one to two weeks; after a deep lesion it can last up to a month, gradually weakening.

A different pattern should cause concern. If the pain does not ease but builds, appears at night, arises in response to heat and takes a long time to pass, if biting becomes more painful every day, or if swelling has appeared, that is a reason to get in touch without waiting for a scheduled check-up. Such symptoms most likely mean that the pulp has not recovered and the tooth will need root canal treatment.

The result is not judged on the day of the visit. A few weeks later, at a follow-up check, the doctor checks the margin of the restoration, the contact point, the bite and the condition of the adjacent gum, and polishes the surface further if needed. After that the tooth is reviewed at routine check-ups every six months, and an X-ray to check hidden areas is taken roughly once every one to two years.

A restoration is not permanent, and this is worth knowing before work begins. According to clinical observations, roughly one to three percent of direct composite restorations fail each year, and the average service life in back teeth is measured in several years, with a range of five to ten most often cited. The spread is wide because service life is affected by the size of the restoration, the number of surfaces rebuilt, hygiene, bruxism and how the chewing load is distributed.

Replacement is a planned part of care, not the result of a doctor's mistake. The key point is this: with each replacement the cavity grows a little, because the old material is removed together with a thin layer of tissue at the margin, so each subsequent restoration is larger than the previous one. This is the main argument for treating early and not letting things reach the deep stage. How long a particular piece of work will last and how the pulp will behave can be forecast only by a doctor after an examination, and even then only approximately.
