I do not recommend a dentist to Nair in Eva dent. Poor-quality canal treatment.
It leaves the tooth open, which definitely cannot be done in any case, this is an outdated technique, the tooth should never be open, neither for children nor for adults.
Its seals that stand on the contact surface fall off after 2-3 months and does not give a guarantee.
In general, I recommend that this doctor undergo advanced training.
Treatment is like in a free state, appreciate your health and look for normal specialists who work with modern methods so that there will be no problems later.
