Dental Hygiene The dental hygiene visit is helps to prevent any dental problems. During the visit the teeth are scaled and polished and the patient is shown the best way to keep the teeth plaque free at home. Scaling and polishing of teeth removes harmful plaque and calculus (tartar) and stain from the teeth. Deeper scaling (debridement) which includes cleaning the roots of teeth may be required for some patients. Each patient’s mouth is unique and therefore your dentist will tailor a treatment plan to your needs. Some people will require one visit however sometimes more visits are necessary. Local Anaesthetic may be used in some cases. We will give you practical advice on how diet and nutrition affects your mouth. This can help you prevent dental decay, erosion (tooth wear) from acidic foods and drinks and also reduce some types of sensitivity.
