Teeth with gaps can be corrected with fillings, crown restorations, dental veneers and orthodontics. 1. Fillings: Usually patients can use composite resin to fill or repair gaps caused by oversized caries, generally filling is low cost and fast process, but there is a possibility of falling off, not very beautiful. 2. Crown restoration: generally there are two kinds of all-ceramic crowns and metal porcelain crowns, with different materials and different prices. Generally speaking, all porcelain crowns have good aesthetics but are more expensive and can be completed by the patient in about a week. 3. Dental Veneers: Usually restored using ceramic restoration bonding techniques, which helps to improve the normal shape of the teeth. They generally have less wear and tear on the teeth and are beautifully colored. 4. Orthodontics: Generally relatively expensive and a relatively long process, but with obvious results and relatively little tooth wear, this is an ideal method of orthodontics. It is recommended that patients with gaps in their teeth should actively seek medical attention and regular treatment under the guidance of a professional doctor.
