Why Does a Dental Crown Sometimes Need to Be Replaced?
A dental crown is designed to be strong. Once it is placed, you may not give it much thought for years, which is exactly what we want. Like your natural teeth, crowns bite and chew every day. Meanwhile, the tooth and surrounding gums can change over time. Eventually, an older crown may need a little attention, and sometimes replacement is the best way to protect the tooth underneath. So, what are we looking for when we check an existing crown?
A Crown Is Only Part of the Tooth
A crown covers and protects a damaged or weakened tooth, restoring its shape, strength, and function, but the natural tooth is still underneath. One particularly important area is the margin, where the edge of the crown meets the natural tooth. We want this area to remain healthy and well sealed.
That is one reason caring for a crowned tooth does not end when the crown is placed. Brushing, flossing, and maintaining appropriate dental care are still important for protecting the natural tooth and surrounding gums.
Can You Get a Cavity Under a Crown?
The crown itself cannot develop a cavity, but the natural tooth can. Decay may sometimes develop around the edge of an older crown. Depending on where it occurs and how extensive it is, we may need to remove the crown to treat the tooth properly.
If the tooth remains restorable, we can then create a new crown to protect it. This is also why we examine crowns even when they feel completely fine. Changes can sometimes begin without causing obvious symptoms.
Crowns Deal with Years of Daily Use
Think about how many times you chew during a single day. Now multiply that by months and years. Dental restorations have to function in a demanding environment. Over time, a crown can wear down or sustain damage. It may chip, crack, or become loose.
Changes in your bite or surrounding teeth can also affect the forces placed on a restoration. None of this necessarily means there was anything wrong with the crown when it was originally placed. It simply means dental restorations, like natural teeth, face years of everyday use.
Your Mouth Changes
The crown is not the only thing we are monitoring. Your gums can change over time. Neighboring teeth may shift. Your bite can change, particularly if you lose another tooth or have additional dental treatment. The natural tooth underneath the crown can also change. That means a crown that has served you well for many years may eventually need to be reevaluated within the mouth you have today.
What Signs Should You Pay Attention To?
Sometimes you will notice that something has changed. A crown may feel loose or different when you bite. You might experience new sensitivity or discomfort when chewing. You may notice a rough or chipped area, or food may start collecting somewhere it didn’t before.
If a crown comes off completely, keep it and contact us instead of trying to reattach it yourself. You also do not need to wait until something hurts. If an older crown doesn’t feel the way it used to, let us know.
Does Every Old Crown Need to Be Replaced?
Age alone does not tell us whether a crown needs replacement. If an older crown remains stable, the tooth underneath is healthy, the margins look good, and everything is functioning appropriately, we may simply continue monitoring it.
At Woolf Dental, we believe treatment recommendations should be based on what you actually need. Sometimes the right decision is replacing a restoration. Other times, the right decision is keeping an eye on it.
Regular Exams Help Us Monitor Your Dental Work
Your dental exams are not just about looking for new cavities. We also check the condition of your existing dental work, including crowns and fillings. We can look for changes in the restoration, evaluate the surrounding tooth and gums, and use X-rays when appropriate to gather information we cannot see during a visual examination. Finding a change early may give us an opportunity to address it before more of the natural tooth is affected.
Protect the Tooth Behind the Crown
A crown may be what you see, but our long-term priority is the natural tooth it protects. If you have an older crown, don’t assume it needs replacing just because it’s been there for years. Care for it like your natural teeth, watch for changes, and let us evaluate it regularly.
If your crown feels loose, uncomfortable, damaged, or simply different than it used to, schedule an appointment with Woolf Dental located in Mesa, AZ. We can evaluate the crown and the tooth underneath it and help you understand whether it needs treatment or can continue doing its job.
