A dental crown is like a sturdy helmet for a damaged tooth. It protects what’s underneath and helps you bite and chew with confidence. Made to be strong and long-lasting, a dental crown is a fantastic solution.
But just like a helmet, it does not last forever. Over the years, daily use and changes in your mouth can mean your old crown needs an upgrade. Knowing the signs of a tired crown is key to protecting your oral health and avoiding more serious problems down the track.
How Long Should a Dental Crown Last?
You can think of a dental crown as a long-term investment in your smile. With proper care, a good quality crown will typically serve you well for between ten and fifteen years.
Some can even last twenty years or more. Its lifespan really depends on a few things. What is it made from? Where is it in your mouth? And most importantly, how well do you look after it?
Even the best crown will eventually show signs of wear. Regular check-ups allow your dentist to keep an eye on it and advise you when it is time for a change.
Key Signs Your Crown May Be Nearing the End of the Road
It is helpful to know what to look out for. Here are the most common signals that your dental crown might need replacing.
Your Gums Are Pulling Back
If you notice your gumline pulling away from the crown, it is a clear sign to pay attention. This recession can create a small gap or ledge between the crown and your gum. This space is a perfect trap for food and bacteria, raising the risk of decay on the underlying tooth.
For older crowns that have a metal base, receding gums might also reveal a dark grey line, which can affect the look of your smile.
You Feel Pain or Sensitivity
A crown should not cause you pain. Any new discomfort is a message from your body. If you feel a twinge of pain when you bite down, or a sudden sensitivity to hot coffee or cold ice cream, it could mean trouble.
The tooth underneath the crown might be decaying, or the crown itself could be loose, irritating the nerve. Do not ignore these feelings. Getting it checked quickly can prevent a small issue from becoming a big one.
The Crown Looks Discoloured or Stained
A well-made crown is designed to match your natural teeth perfectly. Over time, however, the crown itself can become stained from coffee, tea, or other foods. More importantly, if you see a dark shadow or line at the edge of the crown where it meets the gum, this can be a warning sign of decay underneath.
The tooth structure underneath is breaking down and showing through. This is a common reason for replacement.
You Can See Chips or Cracks
Take a close look at your crown. Can you see any visible damage? Even a small chip or a hairline crack is a problem. It compromises the crown’s ability to protect your tooth. Bacteria can enter through the crack, and the structural weakness can lead to a bigger break. If you can feel a rough edge with your tongue, it is definitely time to see your dentist.
The Crown Feels Loose
A crown should feel solid and firmly attached to your tooth. If you notice any movement or a rocking sensation when you touch it with your finger or your tongue, the cement seal has likely broken.
This means bacteria and food debris can get underneath, attacking the vulnerable tooth. A loose crown needs immediate attention to see if it can be re-cemented or if it requires a full replacement.
Your Bite Feels Strange
You know how your teeth normally fit together. If that suddenly feels different, or if one tooth seems to hit first when you bite down, your crown could be the culprit. Crowns can wear down over time or become slightly displaced. This change in your bite can cause discomfort and put unnecessary strain on your jaw joint and other teeth.
What Could Happen If You Delay Replacement?
Ignoring these warning signs is a bit like ignoring a small leak in your roof. The problem will not fix itself, and it will only get bigger and more damaging. Decay under a faulty crown can spread deep into the tooth.
This can lead to a painful infection that might require a root canal treatment. In the worst cases, the tooth could become so damaged that it needs to be taken out. Addressing a problem early is always simpler and more affordable.
How You Can Make Your Crown Last Longer
While no crown lasts forever, you can certainly help it reach its full potential with good care.
- Keep up with a solid oral hygiene routine. Brush your teeth twice a day with a soft toothbrush. Be sure to clean gently around the area where the crown meets your gum. Floss daily to remove plaque from this critical junction. Using an antibacterial mouthwash can also help.
- Visit your dentist for regular check-ups and cleans. These appointments are vital. Your dentist can spot early signs of wear or decay that you might not see yourself. A professional clean removes stubborn plaque and tartar that your toothbrush cannot.
- Protect your crown from unnecessary harm. If you grind your teeth at night, ask your dentist about a night guard. This custom-made appliance will shield your crown and your natural teeth from the intense pressure of grinding. Also, try to avoid bad habits like chewing ice, hard lollies, or using your teeth to open packages.
