Let’s start with the real problem – what is leading to your husband’s excessive tooth wear? Since he is aggressively grinding his teeth, it’s absolutely necessary for him to see a dentist who is familiar with jaw joint disorders. Before any work is done to rebuild his teeth, he needs to have the health of his jaw joints assessed. Additionally, balancing the bite may be necessary.
Unfortunately, while veneers are designed to be durable, they simply aren’t strong enough to stand up against the heavy grinding forces caused by bruxism. Porcelain crowns would probably be a better solution in this situation.
