Can I Get a Cavity Under a Filling or Crown?

A common misconception is that teeth with fillings or crowns are immune to cavities. However, it is entirely possible for decay to develop underneath these dental restorations. In this article, we will discuss how this happens, the signs to look for, and preventive measures to adopt.

Dental restorations such as fillings and crowns are crucial in repairing and protecting damaged teeth, but they are not foolproof against cavities. Decay can develop underneath these restorations due to factors like wear and tear or poor oral hygiene. Over time, fillings and crowns may wear down, crack, or become loose, providing an entry point for bacteria. Additionally, inadequate brushing and flossing can lead to the accumulation of plaque around these dental fixtures, further promoting decay. It's important to recognize signs of underlying decay, such as increased sensitivity or discomfort, and to adopt preventive measures to maintain oral health.

Cost Ranges for Dental Restorations

The cost of dental restorations can vary based on materials, complexity, and geographic location. On average:

• Fillings: $50 to $150 for a single, silver amalgam filling, and $90 to $250 for tooth-colored composite fillings.
• Crowns: $500 to $3,000 per tooth, depending on the material (metal, porcelain-fused-to-metal, or all-ceramic).

Local Tips for Dental Health

• Visit your dentist every six months for regular check-ups and cleanings.
• Consider dental insurance plans that cover routine examinations and procedures.
• Look for local dental schools offering discounted services if cost is a concern.

Frequently Asked Questions

Can a tooth with a filling or crown still get a cavity?

Yes, decay can form underneath fillings or crowns if they become worn or if bacteria accumulate due to poor oral hygiene.

How can I prevent decay in teeth with restorations?

Maintain good oral hygiene by brushing twice a day with fluoride toothpaste, flossing daily, and using an antiseptic mouthwash. Regular dental visits are essential for early detection and maintenance.

What should I do if I notice sensitivity or discomfort in a restored tooth?

Schedule a dental appointment as soon as possible to have the restoration examined. Early intervention can prevent further damage.

How Decay Develops

1. Wear and Tear:
Over time, fillings and crowns can wear down, crack, or become loose, allowing bacteria to seep in.

2. Poor Oral Hygiene:
Inadequate brushing and flossing can lead to the accumulation of bacteria around the edges of fillings and crowns, leading to decay.

Signs of Underlying Decay

1. Sensitivity:
Experiencing increased sensitivity to hot, cold, or sweet substances can be a sign of decay under a filling or crown.

2. Pain:
Discomfort or pain when biting down could indicate an issue beneath a dental restoration.

3. Discoloration:
Dark spots or shadows visible under a filling or crown can be signs of underlying decay.

Preventive Measures

1. Regular Dental Check-Ups:
Frequent visits to the dentist can help in early detection and management of decay under fillings or crowns.

2. Good Oral Hygiene:
Brushing and flossing regularly, especially around crowns and fillings, to prevent plaque buildup.

3. Avoid Sugary and Acidic Foods:
Minimizing the consumption of substances that contribute to tooth decay.

Restoration and Treatment

1. Replacement:
Fillings and crowns may need to be replaced if decay has set in underneath them.

2. Root Canal:
In severe cases where decay has reached the tooth’s nerve, a root canal may be necessary.

Conclusion

While fillings and crowns play a pivotal role in protecting damaged or decayed teeth, they are not foolproof. It’s essential to maintain excellent oral hygiene and regular dental check-ups to ensure the longevity of these restorations and the health of the underlying teeth. If you suspect decay beneath a filling or crown, reaching out to your dentist promptly can ensure appropriate treatment to mitigate further damage and complications.
