Essential Guide to Dental Cavity Filling

From Pregnancy Concerns to Prolonging the Life of Your Smile, we help answer Questions on Dental Cavity Fillings for Optimal Oral Health

Navigating the realm of dental care often includes facing the inevitable prospect of cavity fillings. While the idea may not spark excitement, dental fillings play a crucial role in preventing and treating cavities, offering a solution we can all appreciate.

Types of Cavity

Not all cavities are created equal. Explore the different types of cavities and their characteristics to gain insights into the nature of your dental issue and the best approach for addressing it.

  • Pit and Fissure Cavities: These occur on the chewing surface of molars due to plaque buildup in grooves. Regular, gentle brushing of the molars helps prevent plaque hardening.
  • Smooth Surface Cavities: Found on the smooth sides of teeth, they are rarer but can be managed through dental flossing and regular brushing.
  • Root Cavities: Appearing on the surface root of a tooth, root cavities are more serious, requiring attention to maintain healthy roots. Gentle brushing and sufficient water intake to maintain saliva levels are crucial.

If you suspect any of these cavity types, prompt dental consultation is essential. Contact our dental specialists today for an appointment to address and manage any potential cavity concerns.

Post Care/Aftercare Recovery

What happens after your dental cavity filling? Explore the aftercare steps crucial for a smooth recovery, from dietary considerations to managing potential sensitivities. Proper aftercare ensures the longevity and success of your dental fillings.

  • Post-Dental Filling Diet: Patients often inquire, “What’s safe to eat after a dental filling?” The answer hinges on the filling type. Composite (white) fillings, cured instantly under a blue light, allow immediate eating. Conversely, metal fillings may require a 24-hour wait before consuming solid foods to ensure proper hardening. Waiting until the local anaesthetic wears off is advisable to prevent accidental bites to the cheek, tongue, or lips.
  • Foods to Steer Clear of Post-Filling: For up to two weeks after a dental filling, it’s wise to avoid hard, chewy, or sticky foods. If tooth sensitivity persists, limiting hot or cold drinks and foods is beneficial. Thankfully, there’s no need to delay regular oral hygiene habits; continue brushing twice a day and flossing once daily.
  • Managing Discomfort with Over-the-Counter Painkillers: In case of any physical discomfort post-filling, over-the-counter options like acetaminophen or ibuprofen can provide relief.

How Long Does the Dental Cavity Filling Last?

Ever wondered about the longevity of tooth fillings? The key lies in dedicated dental hygiene and consistent dental check-ups. Regular dentist visits offer the best opportunity to detect early signs of filling issues, such as loosening, shrinking, or new decay on a restored tooth. To maintain optimal oral health, aim for biannual dental check-ups and cleanings.

  • Amalgam Fillings: These can last approximately 10 to 15 years before replacement may be necessary.
  • Composite Resin Fillings: On average, expect these to last around five years.
  • Gold and Porcelain Fillings: Enjoy a longer lifespan with gold and porcelain fillings, ranging from 15 to 20 years.

Can You Undertake Cavity Filling Dental Procedure While You Are Pregnant?

For expectant mothers, dental care is crucial, and yes, fillings are still on the table, provided they are mercury-free. Recognising the potential risks of mercury exposure, health authorities strongly recommend opting for mercury-free fillings during pregnancy. The second trimester is considered the safest time for any dental procedure, including fillings.

Rest assured, dental surgeries incorporate both local and general anaesthesia to ensure the well-being of both mother and baby.


Dental fillings serve as invisible armour, shielding your teeth from further harm. With the right knowledge, care, and regular dental check-ups, these treatments offer not just protection but peace of mind, allowing you to confidently showcase your radiant smile in any situation.
