Tooth Nerve Issues and Tooth Loss: A Patient's Journey - Dentistry

Dental nerves and tooth loss?


I have a tooth that was filled several years ago.
At that time, the dentist said he wasn't sure if it had reached the nerve, so he filled it and told me that if it hurt, I would need a root canal.
Right after the filling, I didn't feel any pain, but once I got home, the pain became unbearable.
I was young at the time and told my dad, "I'm really in pain." He said it was normal, but that night I was in so much pain that I couldn't sleep.
I ended up going to the emergency room in the middle of the night to get painkillers so I could finally sleep.
After that, I endured the pain; it hurt when I touched water, and eating hot or cold food was painful, even breathing in air caused pain.
I endured it for over a year, and then it gradually stopped hurting.
However, suddenly breathing in air would cause intense pain again.
I couldn't take it anymore, so I went to my usual dentist.
I asked the doctor if it could be the tooth that you previously mentioned might need a root canal.
He said it was unlikely since so much time had passed, only noting that my gums looked a bit inflamed and advised me to brush my teeth properly.
I went back home and endured it for a while until it stopped hurting again.
Oh, and previously, I had pain that radiated to my eye.
Four years have passed, and recently I feel pain in my eye again.
I don't know if it's related to that tooth acting up.
I've searched online many times, and I'm worried that the nerve might have decayed further, allowing bacteria to spread to other areas (like my blood vessels, potentially affecting my eyesight and posing serious health risks).
Should I see a dentist for an examination? Should I directly tell the doctor all of this, or should I just ask him to check the nerve of that tooth?
Secondly, the filled tooth cracked when I bit down on it, but I assume they need to check the root for cracks before deciding whether to extract the root as well, right (even though it has already been extracted)? The third-to-last molar was extracted, so does that mean I can only get an implant? Can the remaining teeth be pushed forward like in orthodontics? Thank you, doctor, for taking the time to read this.
Could you please help me with these questions? Thank you.

Hello: If the tooth has been in pain for over four years, it is advisable to proceed with root canal treatment.
Regarding the eyes, it may still be necessary to have an examination by an ophthalmologist.
Additionally, for orthodontics (moving the teeth forward), it is important to confirm whether there is value in moving the teeth forward.
If the remaining teeth may not be retained, moving the teeth forward would be meaningless.
Therefore, it is best to have a comprehensive treatment plan.
Thank you!

Tooth nerve issues and the journey of dealing with tooth loss can be incredibly challenging and distressing for patients. Your experience highlights several important aspects of dental health, particularly concerning nerve damage, tooth sensitivity, and the implications of untreated dental problems.

From your description, it seems that you had a tooth that was filled years ago, with the dentist expressing uncertainty about whether the nerve was affected. This is a common scenario in dentistry, where a tooth may show signs of decay, but the extent of the damage is not always immediately clear. When a tooth is filled, if the decay has reached the nerve, it can lead to significant pain, as you experienced. The pain you felt after the filling, which was severe enough to warrant a trip to the emergency room, indicates that the nerve might have been compromised.

The fact that you experienced pain when exposed to temperature changes or even when breathing in air suggests that the nerve was likely inflamed or irritated. Over time, as you noted, the pain subsided, which could indicate that the inflammation decreased, but this does not necessarily mean that the underlying issue was resolved. In some cases, the nerve can die off, leading to a condition known as pulp necrosis, which can eventually result in an abscess if bacteria invade the tooth.

You raised a critical concern about the potential for bacteria to spread from an infected tooth to other parts of the body, including the bloodstream, which can lead to serious health issues. This is indeed a possibility, especially if the infection is left untreated. It is essential to see a dentist as soon as possible to evaluate the condition of that tooth and determine if further treatment, such as a root canal or extraction, is necessary.

When you visit the dentist, it is crucial to communicate all your symptoms clearly. You should mention your history with the tooth, the pain you experienced, and any other symptoms, such as the pain radiating to your eye. This information will help the dentist make an informed decision about the best course of action. You can ask for a thorough examination of the tooth in question, including X-rays, to assess the nerve and surrounding structures.

Regarding your question about the cracked tooth and whether it needs to be extracted along with the root, this is indeed a common consideration. If the tooth has a fracture that extends below the gum line or if the root is compromised, extraction may be necessary. After extraction, options such as dental implants or bridges can be discussed to restore function and aesthetics.

As for your question about moving teeth forward to fill the gap left by an extracted tooth, orthodontic treatment can sometimes be an option, depending on the overall alignment of your teeth and the specific circumstances. However, this is typically more complex and may require a consultation with an orthodontist to determine feasibility.

In summary, it is crucial to seek dental care promptly to address your concerns. A thorough examination and appropriate imaging will provide clarity on the health of your tooth and the best treatment options available. Don't hesitate to express all your concerns to your dentist; they are there to help you navigate these challenges and restore your dental health.
