Teeth extraction. Biotics should i try?

The first question that I am professionally obligated to ask is whether it is your decision to get a tooth extracted at this age or is the tooth beyond repair in cannot be saved???? Because with the modern equipments and materials we can build up even the most damaged teeth, and there is no doubt about the fact that saving natural tooth is far better than removing it and replacing it with even the best modality of replacement. And as regards your question about the preparations to be done the day before the procedure, it is the best judgement of the dentist who has evaluated the case clinically whether you need any antibiotic coverage or not depending upon the symptoms. And it is not about the antibiotics that you need to "try", it is about the antibiotics that are prescribed according to the clinical situations that demand their use. Premedication is usually not required when we have to do a procedure under local anaesthesia, unlike we do for procedures done under general anaesthesia. Regards.
