It’s common for some dental fillings to last up to 15 years without needing replacement or any kind of treatment. However, not everyone can be as lucky. In fact, some dental fillings may not last even up to 5 years. So what are the reasons for why your cavity could be short-lived and what can Dr. Fleming do about it?
Saliva mixes with the dental filling material.
The longevity of your dental filling will depend on the latter’s ability to adhere to the cavity and the adjacent dental tissues. The better that the dental filling adheres to the tooth, the longer it will last. And while dental fillings have already been designed so that they withstand biting forces and other factors better than they did in the past, saliva can significantly make the dental filling less effective, and cause the dental filling to prematurely fall off. In that case, Dr. Fleming would have to replace the dental filling in Scottsdale AZ or wrap the entire tooth under a porcelain crown.
The tooth cracks under all the pressure.
A healthy, cavity-free tooth might not suffer from any structural problems but when a tooth already has a cavity, and a large one at that, no amount of dental filling will ever allow the tooth to regain the stability it once had when it was still a devoid of any cavity. So because a treated tooth is less structurally sound compared to healthy teeth, this means that they can crack under certain biting forces and with the tooth goes the dental filling.
Teeth grinding can cause leaks and accelerate wear and tear.
Leaks are when sides of the dental filling pull away from the dental tissues, thereby creating some sort of a space on the side of filling. When this happens, bacteria and other dental debris can move into the cavity and infect the rest of the tooth leading to pus formation and even dental infection.
Teeth grinding is the excessive clenching and gnashing of teeth. When this happens, the friction which is generated whenever the two teeth touch and rub against each other can lead to the loosening of the dental filling, enough to create a leak at the side of the tooth. Cracks can also develop which can be repaired for as long as they are detected early enough. However, when the cavity falls off, then the entire dental filling has to be redone completely.
