You can always tell who the better dentists are by the type of facilities they have. Dentists who have a lot of customers or nice offices, have established themselves and proved that they are indeed the best. If a dentist has a lot of customers, it lets you know that he has them for a reason. People that are satisfied with a dentist, normally return. What you eat is a big contributor to cavities. If you eat a lot of sweets or drink a lot of soda, you will be at a higher risk for cavities. Foods that are rich in sugar or starch are eaten by bacteria found in plaque, which will produce acids that eat through teeth. This acid is very harmful to teeth, as it can eat through the dentin and enamel in no time at all. When someone asks for a root canal on the other hand, most of us, including dentists, find it to be very absurd to say the least. Although many aren t aware of this, root canals have been around for many generations. Many years ago, ancient civilizations used this method to save teeth that would have been lost otherwise. Normally, IV sedation is preferred during wisdom teeth removal, as most people don t want to hear the grinding and snapping of the teeth. It works through your veins, as the anaesthesia is inserted into your arm through a vein. If you have chosen either laughing gas or an IV sedation, your dentist will administer either of the two before he gives you shots or goes any further. It s recommended by dentists as being the best, simply because it affects the nerve of the tooth and stops the pain where it starts. Mouthwash can also help tooth sensitivity, providing it contains fluoride. You can also ask your dentist which mouthwash he recommends, as there are several to choose from. The pain will stem from the affected tooth or the jaw, and you ll know it almost immediately. It will start out to be a throbbing pain, then continue to get worse and worse until you get it treated. If you wait too long and allow the infection to spread throughout the tooth, you ll end up having to get it pulled or cut out.
