Arguably the biggest downfall of dentures is that your diet will likely change. There are a range of foods that are unsuitable to eat with dentures. Some people also struggle to speak clearly with dentures. They may slur, mumble or lisp, and are unable to adapt to this, which can seriously affect their confidence.
With dental implants, your teeth are as strong as your natural teeth were. This means you can eat steak, apples, corn on the cob, anything you want. There are almost no limitations. In much the same way, speech with dental implants is normal. There may be a period of adjustment, but people can speak and articulate words clearly.
