Hi. I’m 72 years old and have just been advised by my dentist I need to see a periodontist for a deep clean. My first check up with him will be £175 and he will give me an estimate for treatment needed. I’m just wondering if people who have had this treatment have found it works and is worth the hundreds of pounds it’s going to cost. Obviously I don’t want to loose any teeth but also don’t want to waste money. Any advice will be welcome.
