After my appointment with an endodontist who recommended a crown, my dentist used bonding on the tooth as a more conservative approach. Now the tooth is sensitive and chewing on it hurts. I want this resolved so I can get Invisalign. Should I ask for a crown or an onlay? Thank you. Sonja from Douglasville, GA
Sonja,
Thank you for your question. Dr. Tostado would need to examine and ex-ray your tooth to determine its condition. You may still feel discomfort and sensitivity in the tooth if it is not fully repaired. An accurate diagnosis depends on these factors:
- The crack’s location
- The crack’s length and depth
- Whether the damage is horizontal or vertical
Will a Dentist Recommend a Crown or an Onlay?
A dentist’s recommendation for a crown or an onlay depends on the tooth’s condition and position. Also, not all dentists use onlays. Although an onlay or a crown can restore a tooth, we explain the differences.
Onlay
An onlay is a custom-made restoration that replaces only the damaged portion of your tooth. An onlay covers one or more cusps or peaks of a tooth. An onlay can be gold, ceramic, or porcelain. A porcelain onlay is not strong enough to restore a cracked tooth. A dentist may recommend a gold onlay or a dental crown.
Dental crown
A dental crown is a dental restoration that covers the entire tooth from the gumline up. An extensive crack may require a dental crown. Or, if you already had a crown on a tooth, you could only receive another crown.
Repeated attempts to restore the tooth will further weaken it. Speak with your dentist again to ask about the condition of your tooth and treatment recommendations. Afterward, you may get a second opinion from an advanced cosmetic dentist to compare your options.

The right side of my face is swollen and tight because I broke my second molar tooth two weeks ago. The tooth was weak from a deep silver filling over 15 years old. Last weekend, I heard and felt the tooth crack while eating dinner. Eventually, it broke off in my mouth. I saved the broken piece after I mistakenly bit it. The tooth left a foul taste in my mouth, but I rinsed my mouth with Listerine. I have not thought about replacing the tooth, but it is sore. Will the pain eventually go away?

My upper left molar tooth is sensitive to cold and air. The tooth has a large filling. Two days ago, I went to the dentist, and she used a tool to blow air on the tooth in different areas. She asked if the air made the tooth hurt or sensitive (it did). Afterward, my dentist put a desensitizing agent on the tooth and said the sensitivity should decrease. Is that it? Did I get an accurate diagnosis in five minutes, or was my dentist brushing me off? What has been causing the sensitivity? Dylan from NH
I read online that hydrogen peroxide can disinfect against coronavirus. So, I looked further and found a do-it-yourself mouth rinse recipe that includes hydrogen peroxide. My only concern about rinsing my mouth with it is that I have six porcelain veneers. I know alcohol-based mouthwash can loosen the bonding on veneers, but what about peroxide? Thank you.
