-Repair the crack with a filling
-A root canal if necessary
-Place a crown
And more. If the tooth is broken, it's best to schedule an appointment with a dentist as soon as possible.
My advice would be to have your dentist check the crack and see which one of the two types it actually is, and what the recommendations may be for treatment. They may include any of the following: some form of bonding with composite, something in the crown family like a partial crown, a Bio-mimetic approach to repair the fractured portion of the tooth, or a thin shell of porcelain veneer to cover and hold the crack together.
Thank you for the question!!
Hope this helps!
