Replacing Old Fillings: When and Why It’s Necessary

Replacing Old Fillings

At Crown Dental Group, our dentists offer top-quality filling replacements


Dental fillings play a crucial role in treating cavities and restoring the integrity of damaged teeth.
Over time, these dental restorations may show signs of wear and tear, leading to the question of
when and why they should be replaced. Understanding the factors that influence the need for
filling replacement is essential for maintaining optimal oral health and preventing potential dental
issues. In this blog post, we’ll explore when and why it’s necessary to replace old fillings.

When to Consider Filling Replacement:

Visible Wear and Cracks: Regular dental check-ups enable your dentist to monitor the
condition of your dental fillings. If your dentist notices visible signs of wear, cracks, or rough
edges on your fillings, replacement may be recommended to prevent further damage.

Decay or Leakage: As time passes, the natural wear and tear on fillings can cause them to
become less effective in sealing the tooth. This can lead to bacterial leakage and new decay
forming beneath the filling. If your dentist detects signs of decay around a filling, a replacement
may be necessary to address the issue promptly.

Tooth Sensitivity: An old filling that has started to fail can expose the underlying tooth
structure, leading to increased sensitivity to hot or cold temperatures. If you experience
heightened tooth sensitivity around a filled tooth, consult your dentist to determine if a
replacement is needed.

Change in Bite or Alignment: Worn-out fillings may result in slight changes to your bite or the
alignment of your teeth. This can cause discomfort while chewing and lead to other dental
problems. Your dentist can assess your bite and recommend a filling replacement if necessary.

Age of the Filling: The lifespan of dental fillings can vary based on the material used.
Composite fillings have a lifespan of around 7 to 10 years. If your fillings have surpassed their
expected lifespan, your dentist may advise replacing them as a preventive measure.

Why Filling Replacement is Essential:

Preserving Tooth Structure: Replacing old fillings allows the dentist to remove any new decay
that may have formed beneath the filling. This preserves more of the natural tooth structure,
minimising the extent of restoration needed.

Enhanced Aesthetics: With advances in dental materials, newer fillings can match the colour
of your natural teeth more closely. Replacing old amalgam fillings with tooth-coloured composite
fillings can improve the aesthetics of your smile.

Preventing Further Complications: Promptly replacing old or failing fillings can prevent more
extensive dental issues, such as root canal infections or the need for dental crowns or
extractions.

Improved Functionality: New fillings ensure a proper seal, helping you chew comfortably and
preventing food particles from getting trapped between the filling and the tooth.

Long-Term Oral Health: Regular replacement of old fillings is an integral part of maintaining
your oral health. By addressing minor issues early on, you can avoid costly and invasive
procedures later.
