Press-on veneers are also known as snap-on veneers, clip-on veneers or instant veneers. These are a type of removable prosthetic teeth that fit over your natural teeth, effectively covering up a variety of dental issues. The dental devices are designed to give your teeth a realistic but improved appearance and offer you a natural-looking smile. The good news is that the veneers can transform your smile instantly. Depending on the specific problems you want to address, the appliance will come as either a full or partial arch of your lower or upper teeth.
