Advanced Cosmetic Dental Treatments

Veneers and Bonding: Solutions for Severe Cases

Veneers and bonding are advanced cosmetic procedures designed for severe tooth discoloration or damage that traditional whitening methods cannot address.

Veneers: Thin shells, typically made of porcelain or composite resin, custom-made to cover the front surface of teeth. Veneers provide a complete aesthetic overhaul, masking severe stains, chips, or misshapen teeth. The process involves:

• Tooth Preparation: A small amount of enamel is removed to accommodate the veneer.
• Custom Design: Impressions of the prepared teeth are taken to craft veneers that fit perfectly and match the desired color.
• Bonding: Once fabricated, veneers are permanently bonded to the teeth, transforming their appearance.

Veneers cost anywhere between 5,000 to 25,000 Baht (around 140 to 710 USD, or 130 to 650 Euro) per tooth in Bangkok.

Dental Bonding: A tooth-colored resin is applied to the tooth’s surface and then hardened with a special light. Bonding is ideal for minor imperfections and discolorations, offering a less invasive and more affordable option compared to veneers.

Dental Crowns: When and Why They Are Necessary

Dental crowns are protective covers placed over a tooth to restore its shape, size, strength, and appearance. Crowns are necessary in the following situations:

• Severe Decay or Damage: When a tooth is extensively decayed or damaged, a crown can protect and restore it.
• After Root Canal Therapy: Teeth that have undergone root canal treatment often need a crown to protect the weakened tooth.
• To Cover Severe Discoloration: For teeth that are too discolored to be treated with whitening or veneers, crowns offer a viable solution.

Crowns can be made from various materials, including porcelain, ceramic, or metal alloys, and are custom-made to match the natural color of the patient’s teeth. The process typically involves:

• Tooth Preparation: The tooth is reshaped to allow the crown to fit over it.
• Impression Taking: An impression of the prepared tooth and surrounding teeth is taken to create a custom crown.
• Crown Fabrication: The crown is fabricated in a dental lab to match the tooth’s shape and color.
• Placement: Once ready, the crown is cemented onto the prepared tooth.

A dental crown costs around 7,000 to 30,000 Baht in Bangkok (roughly 200 to 850 USD, or 180 to 780 Euro).

Both veneers and crowns, along with dental bonding, offer effective solutions for severe cases of tooth discoloration, providing long-lasting and aesthetically pleasing results. However, these treatments are more invasive and costly than basic whitening methods, making thorough consultation with a dental professional essential.

Preventive Measures and Oral Hygiene
