Dull ache + alot of treatment "required" with new dentist

[sk5055]

Hello,

I recently switched to a new dentist for a routine cleaning, and afterward, they recommended crowns on teeth #3 and #4, a possible root canal due to “deep decay., in addition to other work that caught me off guard. No issues at previous 8ish month follow-up with old long time dentist.

Since the cleaning (Jan 23rd, 2025), I’ve had on-and-off dull aches, in teeth, but notice in upper right teeth (been about slightly over the week) but no extreme pain. The new dentist suggested its possible because of the xray findings.

Here are my main questions:

• Do my X-rays support the need for crowns and a possible root canal?
• Could post-cleaning sensitivity explain the dull aches?
• Is a CBCT scan justified in this situation?

Additional Info:

• I do not smoke or drink.
• No known medical conditions affecting my teeth.
• Attaching my X-rays for reference.

I’d really appreciate any insights or advice from dental professionals. Thanks in advance!

Based on the x-rays, I can see why he would suggest a crown on tooth #3, due to some secondary decay present beneath the deep existing filling. A crown might seal it better.
I would not recommend a crown on tooth #4.
On the bottom right, you do have some cavities that need fixing, but I don't see a reason for a root canal yet. Don't know why a CBCT was recommended as yet?
I would suggest maybe seeking a second opinion from another dentist.
