Very popular. Of course, the threshold of being a dentist is getting higher and higher, and the study of medicine and practical research is getting stricter and stricter. It costs a lot of money to train a dentist. Orthodontics, treatment, dental implants ... are all expensive. For example, we need dental implants, the materials are different, and the prices are very different. There are hundreds of ordinary metal crown porcelain teeth, and all-ceramic teeth, pure titanium crown porcelain teeth and golden crown porcelain teeth are also more expensive than one. Hundreds, thousands ... all of them. The future of dentists is very good, but it will become more and more strict. We love our teeth. We can use them all our lives.
