Small cavities. After taking X-rays, a larger hole was drilled. It hurt more after the filling was completed?

Hello Dr.
Yang, for the past two weeks, I have experienced slight pain in a specific tooth when eating, but normally there is no discomfort.
After getting it filled, it actually hurts more.
I’m not sure if this is due to the dentist's technique or if I am overly sensitive, so I have some questions I would like to raise for your reference on whether I should continue seeing this dentist.

I just visited a dental clinic for an initial consultation, where the dentist asked an assistant to take X-rays to check for deep decay.
After reviewing the X-rays, the dentist informed me that the cavity was very deep.

Q1: Could the slight pain I feel when eating indicate that the dental pulp is already severely decayed? The dentist mentioned that if I needed a filling, they would have to drill very deep.
However, I don’t feel like my cavity is that severe, but I reluctantly agreed to proceed with the filling.
The dentist drilled very deeply, and it was quite painful.
They kindly asked if I wanted anesthesia, but I was unsure if the dentist would intentionally drill into areas that were not problematic.
It felt like they were drilling too deep, which was very different from my previous filling experiences, especially since this tooth only had slight pain.
I felt it was inappropriate for a healthy tooth to be drilled down to the pulp.
Q2: Is it true that the deeper the filling, even removing non-decayed parts, the more stable it becomes? Or should only the decayed parts be removed? After the drilling was completed, the dentist said I would need a root canal treatment.
I had just undergone significant drilling and could not handle any more pressure, so I quickly declined (with the suction tube in my mouth).
Thankfully, the dentist understood that I just wanted a filling to go home quickly.
The dentist explained that the nerve was inflamed, so they would place medication inside before sealing it, and that it might hurt a lot afterward.
They prescribed painkillers for me.
So, they placed a medication that I am unsure if it is beneficial or harmful to my tooth's nerve; let’s call it a base medication.
Q3: I have never had this base medication placed during previous fillings.
Does it really have therapeutic effects on the nerve? I don’t want to have to undergo drilling again in the future to replace the filling.
The dentist then quickly applied a so-called light-cured resin and skillfully smoothed out the protruding parts.
The dentist said it was okay, and as I was about to get up, I rinsed my mouth with water...
and almost felt weak...
it hurt so much...
which made me want to find another clinic for treatment.
Q4: In my previous fillings, the dentist used two layers of different resins to reduce the discomfort from cold sensitivity.
Is the increasing pain after the filling a way for the dentist to prepare for a future root canal? Or is this just temporary, and once the base medication takes effect, will it improve? Thank you, doctor, for your patience in reading this, and I appreciate any clarification you can provide.
Thank you.

Hello: We apologize for the issues with the medical consultation system, which has prevented us from seeing your questions on our dental consultation platform.
Therefore, there has been a delay in our response.

For general cavities that are not deep, it is usually sufficient to remove the decayed portion and slightly extend the area.
Sometimes, a small cavity may indicate significant underlying damage, and it is difficult to assess the situation accurately at that moment.
Before filling, a base material is typically placed to protect the nerve.
Light-cured resin may cause some sensitivity after the acid etching of the tooth surface.
Generally, cavities are filled first, unless there is persistent sensitivity or pain after the filling, in which case root canal treatment may be considered.
We will observe the situation for 1-2 weeks, and if symptoms persist, further treatment will be necessary.

More Info

Tooth pain after dental procedures, especially fillings, can be a source of significant concern and discomfort for many patients. Your experience raises several important questions regarding the nature of tooth pain, the implications of dental treatments, and the potential for further complications. Let's address your concerns systematically.

Q1: Is the slight pain during eating indicative of severe decay?
The discomfort you're experiencing when biting down on a specific tooth could indeed suggest that the decay is more advanced than initially perceived. When a dentist identifies a cavity as "deep," it often means that the decay has progressed close to or into the pulp chamber, where the nerve and blood vessels reside. If the decay is extensive, it can lead to pulpitis, which is inflammation of the dental pulp, causing pain. The fact that you feel pain when biting could indicate that the nerve is irritated or that there is pressure on the inflamed pulp. It’s crucial to follow up with your dentist to monitor this situation closely, as untreated pulpitis can lead to more severe complications, including the need for root canal therapy.

Q2: Does drilling deeper into the tooth for a filling improve stability?
Drilling deeper into a tooth does not necessarily make it more stable. The goal of a filling is to remove decayed material and restore the tooth's structure. However, excessive removal of healthy tooth structure can weaken the tooth and increase the risk of fracture. Dentists should aim to conserve as much healthy tooth structure as possible while effectively treating the decay. If you feel that your dentist is drilling excessively, it may be worth seeking a second opinion from another dental professional to ensure that the treatment plan is appropriate.

Q3: What is the purpose of the base material placed in the tooth?
The base material, often referred to as a liner or base, is used to protect the pulp and provide a barrier between the filling material and the nerve. It can help to reduce sensitivity and provide some therapeutic benefits, especially if the pulp is inflamed. While some base materials can have a soothing effect on the pulp, they are not a definitive treatment for pulpitis. If the inflammation is significant, further treatment, such as a root canal, may still be necessary. It’s essential to communicate with your dentist about your concerns regarding the base material and its intended purpose.

Q4: Is the increasing sensitivity after filling a sign of future nerve treatment?
Increased sensitivity after a filling can be a common occurrence, especially if the filling is deep or if the pulp is already inflamed. This sensitivity can be temporary and may improve as the tooth adjusts to the new filling. However, if the sensitivity persists or worsens, it could indicate that the pulp is not healing properly, and a root canal may be required. It’s important to monitor your symptoms and report any changes to your dentist. They can assess whether the sensitivity is a normal reaction or a sign of a more serious issue.

In summary, your concerns about tooth pain after a filling are valid and warrant careful consideration. It’s essential to maintain open communication with your dentist about your symptoms and treatment options. If you feel uncertain about the care you are receiving, seeking a second opinion can provide additional reassurance and clarity. Remember, your comfort and understanding of your dental health are paramount in achieving the best outcomes.
