Tooth implant is a surgical fixture procedure that replaces natural tooth roots with a metal-like instrument called screw. Tooth implant treatment is performed when a tooth is damaged or lost due to injury or accident. The missing tooth is replaced with an artificial tooth that looks and functions like real ones. Tooth implants are a better alternative from other prosthesis like dentures or dental bridges that don't fit well in the missing space. But tooth implant cost is bit expensive as compared to other prosthesis. Implants can also be an option, when a lack of natural teeth roots don't allow building denture or bridgework tooth replacements. The procedure of dental implant surgery depends on the type of implant needed and the condition of your jawbone. If your bone is healthy then only tooth implants are considered to be fixed. Dental implant surgery involves several procedures. The major benefit of implants is solid support for your new teeth and its durability. The process can take many months because the bone requires time to heal.
