Can I transfer to my dentist's new clinic if my dentist has changed jobs?

Hi! From the picture, it appears that you could have had upper and lower jaw surgery, as well as a sliding genioplasty and braces. Generally, this should not affect non-invasive facelift treatments. You should be able to undergo most of these such as high intensity focused ultrasound (HIFU - e. g. Ultraformer, Ulthera), fractional energy devices (such as fractional picosecond, fractional lasers, fractional radiofrequency), fillers, Dysport dermalift, subdermal lasers/radiofrequency or threadlifts. These should be safe provided the proper precautions are taken.

Dentists choose treatment plans based on many different factors. Some of these factors have nothing to do with clinical data. As a patient, your dentist should go through the different treatment options with you so that you understand the treatment itself, and the long term maintenance required with that selection. Keeping the tooth by performing root canal treatment and a crown may mean that the tooth may still crack further and require extraction at a later date.
