10 Signs It’s Time to Replace Old Fillings
Dental fillings repair cavities, protect weakened tooth structure, and allow you to bite and chew comfortably. However, even a well-placed filling may eventually wear down, loosen, or become damaged. Knowing when to replace fillings can help you address small concerns before decay or fractures cause more extensive problems.
A filling does not necessarily need attention simply because it is old. Its condition matters more than its age. Regular dental exams allow us to evaluate the restoration, check the surrounding tooth, and recommend treatment when it is genuinely needed.
How Long Do Dental Fillings Last?
The lifespan of a filling depends on its material, size, location, and daily use. A small filling in a front tooth may experience very different forces than a large restoration in a molar.
Other factors that can affect longevity include:
- Teeth grinding or clenching
- Chewing hard foods or ice
- Oral hygiene habits
- Recurrent tooth decay
- Changes in your bite
- Trauma to the tooth
- The amount of natural tooth structure remaining
Rather than relying on a specific timeline, watch for the following signs and continue attending routine dental checkups.
-
You Feel Pain When Biting
Pain or a sharp sensation when you bite down can indicate that a filling is loose, damaged, or interfering with your bite. It may also point to a crack in the tooth beneath or around the restoration. Because several dental problems can cause biting pain, an examination is necessary to identify the source.
-
The Tooth Has Become Sensitive
New sensitivity to hot, cold, sweet, or acidic foods may develop if a filling no longer seals the tooth effectively. Temperature changes can reach the sensitive inner layers through a small opening or worn area. Brief sensitivity does not always mean the filling has failed. Persistent or worsening symptoms, however, deserve professional attention.
-
You Notice a Visible Crack
You may be able to see a fracture in the restoration when looking in a mirror. Cracked fillings can allow bacteria and food particles to enter areas that are difficult to clean, increasing the risk of decay beneath the restoration. Avoid chewing hard foods on that side until the tooth can be evaluated.
-
Part of the Filling is Missing
A filling may chip or break, leaving a rough spot, indentation, or visible opening. You might also find a small piece of material in your mouth while eating or brushing. Even if the tooth does not hurt, the exposed area may be vulnerable to bacteria and additional damage. Schedule an appointment rather than waiting for discomfort to appear.
-
The Filling Feels Loose
A stable restoration should not shift when you chew or touch it with your tongue. Movement may mean the bond between the filling and tooth has weakened. Do not attempt to press, glue, or otherwise repair a loose filling yourself. Household adhesives are not safe for use in the mouth and can make professional treatment more difficult.
-
Food Regularly Gets Stuck Around It
Food that repeatedly collects around the same tooth may indicate that the filling’s shape has changed or that a gap has developed along its edge. This can irritate nearby gum tissue and make cleaning more challenging. Frequent floss shredding or catching near the restoration may be another clue that an edge has become rough or uneven.
-
Your Bite Feels Different
A damaged or shifting restoration can change how your teeth meet. You may feel as though one tooth touches first or notice discomfort when chewing. Bite changes should be evaluated promptly. Continuing to place uneven pressure on the tooth could contribute to additional wear or fracturing.
-
The Filling Has Rough or Sharp Edges
Running your tongue over the tooth may reveal an edge that feels jagged, sharp, or unusually rough. This could result from everyday wear, a small chip, or a fracture. Sharp areas may irritate your tongue or cheek. They can also signal that the restoration no longer has its original contour and integrity.
-
The Tooth or Filling Looks Discolored
Some filling materials naturally change appearance over time. However, darkening around the restoration’s edges or a visible shadow beneath the tooth may indicate staining, leakage, or recurrent decay. Discoloration alone does not confirm a problem. We may need an examination and dental X-rays to determine what is happening below the visible surface.
-
You Have Persistent Toothache or Swelling
Ongoing pain, throbbing, gum swelling, or tenderness around a filled tooth can indicate advanced decay, inflammation, or infection. These symptoms require timely care, especially when accompanied by fever, facial swelling, drainage, or a bad taste. Depending on the condition of the tooth, treatment could involve a new filling, crown, root canal, or another restorative option. Prompt evaluation may provide more opportunities to preserve the tooth.
