"Can dentist build up teeth that r low" refers to the process of dental restoration, also known as dental filling, in which a dentist repairs damaged or decayed teeth by filling them with a durable material. This restoration process helps restore the tooth's functionality, strength, and aesthetics.
Dental restoration is crucial for maintaining oral health. It prevents further decay, alleviates pain, and improves chewing ability. Historically, dentists used gold, amalgam, and porcelain for fillings. Nowadays, composite resins, which are tooth-colored and blend seamlessly with the natural tooth structure, are widely used.
