Tooth hardening gum recession is usually possible with veneers, but veneers are not recommended if the gum recession is more than two-thirds of the tooth root. Dental veneers are a method of restoring the form and function of missing teeth through medical means, using artificial materials. Gum recession, a disease that is most likely to occur in the middle-aged and elderly populations, usually results in longer teeth, larger gaps between teeth, and even exposed roots and loose teeth. If the teeth are hard and the gum recession is mild, not reaching two-thirds of the root, veneers are possible in this case. But for gum recession is serious, more than two-thirds of the root and accompanied by loose teeth, it is not recommended for veneers. Whether hard teeth and gum recession patients can be veneered, it is recommended to go to the hospital to improve the relevant examination, according to the doctor’s guidance and advice to make the appropriate choice.
