Over time our teeth begin to weaken and become more susceptible to problems such as decay, cracks, and discoloration. If you feel your smile isn’t what it once was, crowns can help you recover your smile. If your dentist notices that a tooth is decayed or seems weakened/cracked, a crown may be necessary to prevent further insult to the affected tooth. In cases of large cracks and decay, a filling or bonding will not be sufficient.
