Will I need a crown after my root canal treatment?
If a molar or back tooth needs root canal treatment, because it has broken or is very decayed, it will usually need a crown to hold it together afterwards. It depends on how much of the healthy tooth structure is left and what the risk is of the tooth cracking in half. Root canal-treated teeth are more brittle than other teeth and often need a crown to prevent breakage. On the other hand, a front tooth that is fairly intact may not need a crown after root canal treatment. Sometimes a large filling can be placed instead of a crown to hold a tooth together. Ask your dentist for advice, as each tooth is different.
