Probably nerve exposure due to secondary Infection.

Detailed Answer:
Thanks for the query..

As you have crown over the four lower teeth and now they are sensitive to hot and cold, then it can be Probably nerve exposure on one or multiple crowned teeth..

It can be due to decay in teeth, fracture of the teeth, gum recession etc..

So first of all can you please tell that were your teeth Root canal treatment before capping?

Is the sensitivity always present?

Can you see any roots of teeth exposed due to gum recession?

Are any of crowned teeth loose?

Is there any pain or discomfort when you bite on the crowned teeth?

Can you observe any food accumulation between the crowns and teeth?

Please revert back with answers..

Brief Answer:
You should get an x ray done..

Detailed Answer:
Thanks for the reply..

If your teeth were root canal treated then sensitivity is not possible because in root canal treatment nerve is removed from the tooth that are responsible for sensation..

So the problem can either be due to deep gum infection and / or Infection below the root tips of the teeth that is periapical Infection..

So my suggestion is to once get a clinical examination and an x ray done..

Initially a course of antibiotics like Amoxicillin and metronidazole, anti inflammatory painkillers like Ibuprofen can be advised..
Also apply Metronidazole gel over the gum and massage..
Do warm saline gargles..

Please upload the x ray and a picture of the area of the crowned teeth for further information..
