A. Hi John. Valplast dentures are designed to be more flexible in the mouth to feel more natural and also to aid retention as it grips onto your existing teeth. Alterantively, you can have an implant retained denture that stays in purely with locatrs that clip onto the implants. I would recomend that you get a consultation to discuss your options at a cosmetic dental practice. I would be more than hapy to see you at any of my Manchester based KISSDENTAL clinics for a free consultation.
