    A: Diamond Certified dentists use top-quality brands like Sensodyne, GUM, Tom's of Maine, DenTek and Reach.
    Q: What types of gum disease treatments do dentists offer?
    A: Dentists offer a range of gum disease treatments depending on the severity of the condition. For early stages of gum disease, also known as gingivitis, professional cleaning and improved home care may be sufficient. If the disease has advanced to periodontitis, a deeper cleaning procedure called scaling and root planing might be needed. This involves scraping off the tartar from above and below the gum line and smoothing out rough spots on the tooth root. In severe cases, surgical treatments such as flap surgery (to clean and secure the gum to the teeth) or bone and tissue grafts (to regenerate any lost gum or bone) might be required. Dentists may also prescribe antibiotics or antimicrobial mouthwashes to help control the bacterial infection.
