At Astro Dental, we work hard to improve the smile of patients across Caerphilly and South Wales. We’re on a mission to improve the aesthetic qualities of teeth — a process that involves straightening and whitening. We charge £300 for composite bonding per tooth we usually would recommend 2 weeks of whitening at a cost of £300. We offer interest free finance for 12 months regardless of your credit score. Composite bonding involves the use of a white filler to repair chips, smooth imperfections and improve both the shape and colour of teeth.
