Dental inlays are a type of dental restoration used to repair teeth that have suffered damage or decay but are not so extensively damaged that they require a crown. This treatment is an excellent option for patients who need more than a filling but less than a full crown. In this guide, we will cover everything you need to know about dental inlays, including what they are, the procedure involved, their benefits, and how to care for them.
What Are Dental Inlays?
A dental inlay is a custom-made restoration that fit into the grooves of a tooth. They are typically used on the chewing surfaces of the back teeth (molars and premolars) and are designed to restore the function and appearance of a damaged tooth. Unlike regular fillings, which are applied directly into the cavity and moulded during the visit, inlays are fabricated outside of the mouth, usually in a dental lab, and then bonded to the tooth.
When Are Dental Inlays Used?
Dental inlays are used in various situations:
Large Cavities: When a cavity is too large for a regular filling but not extensive enough to require a crown.
Damaged Teeth: To repair teeth that are cracked or fractured, particularly if the damage is confined to the chewing surface.
Decay Removal: When significant decay has been removed from the tooth, leaving behind a large space that needs to be filled.
Old Fillings Replacement: To replace old or damaged fillings that no longer adequately protect the tooth.
Materials Used for Dental Inlays
Inlays can be made from several types of materials, each with its benefits:
Gold: Highly durable and long-lasting, gold inlays are resistant to wear and corrosion. They are biocompatible and gentle on the opposing teeth. However, their metallic colour is not aesthetically pleasing to many patients.
Porcelain: These inlays are very popular due to their natural appearance. They can be colour-matched to the surrounding teeth, making them virtually indistinguishable. Porcelain inlays are also durable and resistant to staining.
Composite Resin: Made from a tooth-coloured material, composite resin inlays are less expensive than porcelain but not as durable. They are a good option for patients looking for a more affordable aesthetic solution.
The Dental Inlay Procedure
The process of getting a dental inlay typically involves two visits to the dentist:
First Visit: Preparation and Impressions
- The dentist begins by numbing the affected area with a local anaesthetic.
- Decay or damaged areas of the tooth are removed, leaving behind a clean, prepared cavity.
- An impression of the prepared tooth is taken. This impression is sent to a dental lab where the inlay will be custom-made.
- A temporary filling is placed to protect the tooth until the inlay is ready.
Second Visit: Placement of the Inlay
- The temporary filling is removed, and the tooth is cleaned.
- The dentist checks the fit of the custom inlay and makes any necessary adjustments.
- Once the fit is perfect, the inlay is bonded to the tooth using a strong dental adhesive.
- The dentist polishes the inlay and the surrounding tooth to ensure a smooth finish.
Benefits of Dental Inlays
Dental inlays offer several advantages:
Durability: Inlays are made from strong materials that can withstand the forces of chewing and last for many years.
Aesthetic Appeal: Porcelain and composite resin inlays can be colour-matched to your natural teeth, providing an attractive, seamless appearance.
Preservation of Tooth Structure: Inlays require less removal of the healthy tooth structure compared to crowns, helping to preserve more of your natural tooth.
Improved Fit: Custom-made to fit your tooth precisely, inlays provide a better fit than traditional fillings, reducing the risk of future decay and damage.
Comfort: Inlays fit snugly within the grooves of your tooth, providing a comfortable bite and preventing food from becoming trapped.
Caring for Dental Inlays
Proper care and maintenance are essential to ensure the longevity of your dental inlays:
Oral Hygiene: Brush your teeth twice a day with fluoride toothpaste and floss daily to remove plaque and prevent decay around the inlay.
Regular Dental Check-Ups: Visit your dentist every six months for check-ups and professional cleanings. Your dentist will monitor the condition of your inlays and overall oral health.
Avoid Hard Foods: While inlays are durable, avoid chewing on very hard foods and objects, such as ice or pens, which can damage the restoration.
Mouthguards: If you grind your teeth at night, consider using a mouthguard to protect your inlays and prevent damage to your teeth.
Potential Risks and Complications
While dental inlays are generally safe and effective, there are some potential risks and complications:
- Tooth Sensitivity: You may experience temporary sensitivity to hot and cold after the inlay is placed. This usually subsides within a few days.
- Allergic Reactions: Some patients may have allergic reactions to the materials used in the inlay. If you have known allergies, discuss them with your dentist beforehand.
- Dislodgement: In rare cases, an inlay can become dislodged. If this happens, contact your dentist immediately to have it re-bonded.
Conclusion
Dental inlays are an excellent solution for restoring damaged or decayed teeth, providing durability, aesthetic appeal, and a comfortable fit. By preserving more of the natural tooth structure and offering a custom fit, inlays are a superior alternative to traditional fillings for certain dental issues. If you think you might benefit from a dental inlay, consult with your dentist to discuss the best treatment options for your needs. With proper care and regular dental visits, your inlays can help maintain your smile’s health and beauty for many years to come.
