As the years go by and you have dental work done, you may need to have one or more teeth filled. Dental fillings don’t last forever, of course, and we will eventually need to replace them. Tooth-colored composite fillings last about five years, and amalgam fillings last about ten years.
But how many times can you replace a filling? And at what point does a filled tooth require a dental crown? This is a great question! The answer is that if the decay or damage involves more than half the width of the tooth, we need to cover it with a dental crown at our Allentown, PA dental office.
When the tooth has reached this stage, it has been significantly weakened and is prone to fracture or cracking. In some cases, our dentists may recommend a dental crown if an older filling has cracks or shows signs of stress.
Dental Crowns to Protect Teeth
The purpose of a dental crown is to restore form and function to a decayed or damaged tooth. When we place it on your tooth, the crown absorbs chewing forces to protect the tooth from further damage. It also restores your appearance, because our all-porcelain dental crowns blend beautifully with your smile.
If you’re concerned about a large filling and think you might need a dental crown, please call our Allentown, PA dental office to schedule a dental appointment.
