The fact of cosmetic dentistry all over is the same; there will be some pain, so why go through the pain of searching for a dentist that doesn't suit your needs? A small amount of research and asking the correct questions of the dentists you are looking into will ensure that you get the right dentist for the work you need done.
You may choose to get veneers or implants, or jot to replace a tooth you lost in an injury or accident. Whether it is a large and complicated surgery to completely replace your teeth with dental implants, or a small procedure to put a few veneers on some unkempt teeth, you are putting your mouth in the hands of a stranger. You will want a dentist that is very familiar with the procedure you want, and not trying to push you into anything that you don't want.
You'll want to search for a dentist that has past experience in the option you have picked for your cosmetic procedure. If you require implants, and your dentist has done a thousand veneers, but has only done one or two dental implants, you are better off to seek out a dentist that has more experience to perform your implant surgery or vice versa.
It is important to ask the right questions, such as how much experience the dentist has had with each procedure, and how familiar they are with the latest equipment, materials, and surgeries. If a dentist is using outdated materials and procedures, even if they have had years of experience, it may be better to go to a more innovative office that has the better, more up-to-date manner of doing surgery. Your dentist should be keeping up with the technology available to them.
You must also consider cost, and if the dental procedure can be covered on your insurance. Sometimes the exact same procedure done by dentists with similar experience can be priced very differently, just based on the dentist's location and overhead. It pays to shop around for dental procedures, as this could save you money.
