Dental fillings are one of the most common treatments used to restore teeth after cavities. They help prevent further decay, preserve your natural tooth structure, and support your bite. But like all dental work, fillings don’t last forever. Over time, they can wear down, crack, or fall out, making your tooth vulnerable again.
In this blog, we’ll explore how to know when it’s time to replace your fillings, and what you can do to protect your smile for years to come.
How Long Do Fillings Typically Last?
Dental fillings can last anywhere between 5 to 15 years, depending on the type of material used (amalgam, composite, gold, or ceramic), your oral hygiene habits, and how much stress the filling undergoes from chewing or grinding.
While some fillings may last longer with proper care, they are not considered permanent. Over time, tiny gaps can form between the filling and the tooth, allowing bacteria to sneak in and cause new decay.
Signs You Need to Replace a Filling – Insights from a Dentist in SW Calgary
A skilled dentist in SW Calgary will typically check the condition of your fillings during your regular check-ups. However, you should also watch out for these common signs between visits:
1. Tooth Sensitivity or Pain
If your tooth suddenly becomes sensitive to hot, cold, or sweet foods, it could be a sign that your filling is wearing out or that new decay has developed around it.
2. Visible Cracks or Damage
Look in the mirror or feel with your tongue—if your filling feels rough, cracked, or chipped, it's time to get it checked.
3. Discoloration Around the Filling
If you notice any dark spots near your filling, it may indicate decay underneath.
4. Loose or Missing Filling
Sometimes fillings can fall out completely, especially if they were old or damaged. If you feel a hole or gap where the filling used to be, you should visit a dental office immediately.
5. Bad Breath or Bad Taste
Persistent bad breath or a strange taste in your mouth may suggest decay or bacterial buildup beneath a damaged filling.
When to See an SW Calgary Dentist Near You
If you notice any of the signs above or it’s been a while since your last dental check-up, it may be time to see an SW Calgary dentist near you. Dentists use advanced diagnostic tools like digital X-rays and intraoral cameras to inspect your fillings closely. Even if there are no outward symptoms, they may detect early issues before they become painful or expensive.
Many patients delay treatment because they aren’t in pain, but remember—dental problems often start silently. Replacing a filling early can save you from needing a root canal or crown later on.
Why Do Fillings Fail?
There are several reasons why fillings may break down:
- Age: Older fillings naturally wear out over time.
- Chewing Habits: Grinding, biting nails, or chewing on hard items (like ice or pens) can weaken fillings.
- Poor Oral Hygiene: Bacteria can slip into the edges of the filling and cause decay underneath.
- Temperature Changes: Repeated exposure to hot and cold foods can cause materials to expand and contract, leading to cracks.
What Happens During a Filling Replacement?
The process is usually quick and painless. Your dentist will:
- Numb the area around the tooth.
- Remove the old filling and any decay underneath.
- Clean and prepare the space.
- Place a new filling—usually tooth-colored composite for a natural look.
- Polish and adjust the filling for comfort and proper bite.
Most appointments are completed in less than an hour, and you can resume normal activities shortly afterward.
Can You Upgrade Old Fillings?
Yes! Many patients are choosing to replace silver amalgam fillings with white composite fillings for cosmetic reasons. Composite resin not only blends in with your natural teeth but also bonds better and preserves more of the original tooth.
If you’re concerned about the look of your smile or have older metal fillings, talk to your dentist about whether an upgrade would benefit you.
How to Prolong the Life of Your Fillings
Maintaining healthy fillings comes down to good oral habits:
- Brush twice a day with fluoride toothpaste.
- Floss daily to remove plaque between teeth.
- Avoid hard and sticky foods that could damage fillings.
- Visit your dentist twice a year for check-ups and cleanings.
Your dentist may also recommend a night guard if you grind your teeth at night, which can extend the life of your restorations.
