There are a few potential downsides to dental implants, though they are typically minor and easily treatable. The first is that the implant procedure can be slightly more expensive than other options, such as dentures. Additionally, there is a small risk of infection at the implant site. This can usually be treated with antibiotics, but in rare cases may require the implant to be removed. Finally, some people experience slight discomfort and soreness after the surgery, though this usually goes away within a few days.
