Dental filling issues?


Hello Doctor,
Around December, I went to the hospital for a dental cleaning, and the dentist informed me that there was a cavity between my upper right back teeth, specifically an interproximal cavity.
I was already aware of this because another dentist from the same hospital had mentioned it a few years ago during an X-ray, but she advised me to leave it alone at that time.
Later, I couldn't schedule an appointment with that dentist for a cleaning, so I switched to another one.
The current dentist told me that the cavity has progressed a bit deeper, and if I don't get it filled soon, I might need a root canal.
The dental assistant then explained something about 3D modeling and presented a cost estimate of NT$20,000.
As I am still a student, I don't have that much money, so I decided to discuss it with my parents first.
My mother suggested that I visit her dentist.
I initially planned to go to Mackay Memorial Hospital, but I couldn't get an appointment on short notice, so I went to another dental clinic.
The older dentist took an X-ray, then filed down the tooth a bit and filled it.

By the end of February, I started experiencing pain in that area again.
After consulting the dentist who filled my tooth, he said it might be due to the filling material being too high, so he filed it down again.
After that, I felt less pain when biting.
However, it's been less than a week since the last adjustment, and I still experience sensitivity when drinking hot or cold beverages, and sometimes I feel pain in the morning.
It’s not as painful as before when biting, but I’m worried that the initial high filling made the tooth's nerve more sensitive.
I’m really concerned, and since a filled tooth cannot be refilled within a year, I shouldn't seek treatment at another clinic, right? I worry every day about whether I really need to use 3D modeling for the filling, but I don't have that kind of money...
I really don't know what to do.
Thank you!

Cavities between teeth can be filled using traditional composite resin or silver amalgam (which is covered by health insurance), or with 3D computer-assisted ceramic blocks, although this option requires out-of-pocket payment.
If there is sensitivity or pain after the filling, it may indicate that the original cavity was extensive and close to the nerve.
If the sensitivity persists, it may be necessary to consider root canal treatment.
It is advisable to consult a dentist for further examination.

Tooth filling issues can be quite concerning, especially for students who may not have the financial means to address dental problems immediately. It sounds like you have been through a challenging experience with your dental care, and it's understandable to feel anxious about your situation. Let's break down your concerns and explore potential solutions.

Firstly, it’s important to understand that cavities, especially those located between teeth (interproximal cavities), can progress quickly if not treated. When a dentist identifies a cavity that is "a little deep," it indicates that the decay has penetrated beyond the enamel and into the dentin, which can lead to more serious issues, such as pulpitis (inflammation of the dental pulp) if left untreated. This is likely why your dentist emphasized the urgency of getting a filling to prevent the need for a root canal.

You mentioned that you initially received a quote for a filling that seemed excessive, particularly as a student. Dental costs can vary significantly based on the type of filling material used, the complexity of the procedure, and the location of the dental practice. It's worth noting that while 3D modeling and advanced techniques can provide precise results, they are not always necessary for every filling. Traditional fillings, especially for cavities that are not too deep, can often be done effectively without such advanced technology.

After your initial filling, it’s concerning that you are still experiencing sensitivity and pain. Sensitivity to hot and cold can occur for several reasons:
1. High Filling: If the filling is too high, it can cause discomfort when biting down, as you experienced. Your dentist's adjustment may have alleviated some of that discomfort, but it’s possible that the filling still needs further refinement.

2. Nerve Sensitivity: After a filling, especially if the cavity was deep, the nerves in the tooth can become more sensitive. This sensitivity may diminish over time, but it can take several weeks for the tooth to settle down.

3. Material Reaction: Some filling materials can cause sensitivity, particularly if they are not fully compatible with your tooth structure or if they were placed under less than ideal conditions.

Given your situation, here are some steps you can take:
- Follow-Up Appointment: It’s crucial to have a follow-up appointment with your dentist to discuss your ongoing sensitivity. They can assess the filling and determine if further adjustments are needed or if there’s another underlying issue.

- Seek a Second Opinion: If you feel uncomfortable with the current dentist or their approach, seeking a second opinion from another dental professional can provide you with more options and potentially more affordable solutions.

- Discuss Financial Options: Many dental offices offer payment plans or financing options for students. Don’t hesitate to discuss your financial concerns with your dentist; they may be able to work with you to find a solution that fits your budget.

- Maintain Oral Hygiene: Continue to practice good oral hygiene, including brushing twice a day with fluoride toothpaste and flossing daily. This will help prevent further decay and sensitivity.

- Monitor Symptoms: Keep track of your symptoms. If the pain worsens or if you experience swelling, it’s essential to seek immediate dental care, as these could be signs of an infection.

In conclusion, while it’s understandable to be worried about your dental health and the associated costs, addressing these concerns with your dentist and exploring your options can help you find a manageable solution. Remember, your oral health is important, and there are professionals who can assist you in navigating these challenges.
