Concerns About Ongoing Pus After Root Canal Treatment – Is It Wise to Proceed with Permanent Filling?
Hello everyone! I’m a 17-year-old facing a periapical abscess as part of my dental issues. I’ve been receiving root canal treatment for an upper front tooth, continuing for about a month now, with three appointments completed thus far. My endodontist has been using a dressing, probably calcium hydroxide, in between these sessions. However, I’m still experiencing **consistent pus drainage**, which I sometimes manage to extract myself. Recently, I’ve also observed a **slight tint of blood in the pus**. Fortunately, the tooth itself does not hurt, and there has been no swelling or significant discomfort related to it. My endodontist intends to apply the final filling next week, but I’m feeling uneasy because the pus continues to drain. Shouldn’t the infection be resolved, and all drainage ceased before proceeding with sealing the tooth? Is the ongoing pus discharge, particularly with traces of blood, indicative of a lingering infection or a different complication? Moreover, I’m curious about whether this infection could potentially impact my **adjacent teeth** or if it’s generally limited to just the one undergoing treatment. Could I require root canal work on nearby teeth, or is it typical for the infection to remain localized? Has anyone experienced anything like this? Is it common or prudent to complete the RCT and permanently seal the tooth while pus (and some blood) is still present? What inquiries should I be making to my endodontist to ensure I'm getting the best care possible? Thank you for any advice you can provide!

It’s understandable to feel concerned about ongoing pus drainage after your root canal treatment, particularly with the addition of blood. This situation indicates that your tooth may still have some infection or inflammation that needs to be addressed before sealing the tooth permanently.
Explanation:
Root canal therapy is performed to remove infection from inside the tooth and prevent further problems. Persistent pus, especially with blood, suggests that the infection hasn't completely cleared. Although you’re not experiencing pain or swelling, the presence of pus indicates that your tooth might not be fully healed, which could lead to complications if sealed prematurely.
Infections can sometimes be localized, but they can also spread to adjacent teeth. It's crucial to resolve any existing infection to ensure your overall dental health.
Next Steps:
-
Discuss Your Concerns with Your Endodontist: Before proceeding with the final filling, voice your worries about the ongoing pus and blood. Ask about the reasons for sealing the tooth now despite these symptoms and if it’s advisable to wait until the drainage stops.
-
Request an X-ray or Assessment: Ask if a follow-up X-ray or clinical evaluation is needed to check the healing progress and assess the infection's state. This will help identify whether further treatment is necessary.
-
Monitor Symptoms: Keep track of any changes in the drainage, including amount, color, or associated sensations (like new pain). Noting these can be helpful for your endodontist during your next visit.
-
Consider a Second Opinion: If you're still uneasy after discussing with your current endodontist, seeking a second opinion from another dental professional may provide additional clarity and comfort.
Additional Questions to Ask Your Endodontist:
- What are the potential risks of sealing the tooth while pus is still present?
- How can we ensure that the infection does not spread to adjacent teeth?
- What are the options if the infection persists after the final filling?
It's great that you're being proactive about your dental health. Continue to ask questions and seek clarity to ensure you're comfortable with your treatment plan.

Morning Discomfort: Ongoing Shoulder, Neck, and Arm Issues
# HEALTH PROFILE I’m a 32-year-old male, weighing 235 pounds and standing at 5 feet 11 inches tall. My body composition includes a mix of fat and muscle. Maintaining an active lifestyle due to my job, I began engaging in high-intensity workouts twice weekly starting mid-December. To alleviate soreness, I incorporate daily stretching into my routine and sometimes utilize a trigger point cane for self-massage. Previously, I struggled with alcohol and opioid addiction, but since early 2023, I have been substance-free. Currently, I smoke a pack of light cigarettes daily but don’t plan on quitting soon. At the age of 18, I experienced a fall that led to the herniation of four discs (L4, L5, S1, S2), pinching a nerve and causing severe pain, which contributed to my previous substance abuse. After undergoing IDD Therapy and physical therapy, I regained my mobility and reduced discomfort. I managed to quit pain medication at age 22, but turned to Kratom until I sought rehabilitation at age 29, leading to a cleaner lifestyle since then. ### Medications: - **Ibuprofen**: 2000mg daily, taken as 4 pills in the morning, 3 at lunch, and 3 at dinner. Initially, I was taking 12 pills daily due to persistent back pain but have reduced this for the sake of my stomach and kidneys. With the onset of shoulder pain, I adjusted my morning dosage from 3 pills. - **Clonidine**: 0.1mg, taken three times daily for anxiety management and blood pressure. This has been beneficial for me since it was prescribed in rehab. - **Suboxone**: 2.5mg daily, also prescribed during rehab. - **Pantoprazole E**: 20mg in the morning for GERD, which I’ve been using for nearly a year without any adverse effects. I regularly consume Poppi prebiotic soda and dried fruits to help manage my GERD while enjoying treats like cheese and bacon occasionally alongside lean proteins, vegetables, and fish. - **Calcium Supplement**: Taken every other day to counteract the calcium depletion caused by Pantoprazole. - **Turmeric Supplement**: Taken in the morning to help with inflammation and warmth, valuable given my local climate. ### Employment I work as a school bus driver and also drive for GrubHub on Friday evenings and Saturdays when my schedule permits. As a standby bus driver, my work often involves janitorial responsibilities such as sweeping, mopping, and cleaning. My driving time averages around two hours in the morning and evening, alongside four hours on Fridays and eight hours on Sundays. ### MAIN ISSUE I wake up every morning with persistent shoulder, upper back, and neck soreness. When I sleep, regardless of the side, the arm I lay on becomes numb, accompanied by ongoing weakness throughout the day. Despite having purchased a new hybrid spring and foam Dreamcloud mattress, my discomfort hasn’t improved. I’ve experimented with various pillow types to relieve neck and shoulder tension, but without success. Although I typically sleep on my side, I instinctively roll over even when attempting to sleep on my back. On nights that I rest poorly, my morning pain is notably lessened, possibly due to increased movement during sleep. Grinding my teeth at night leads me to use a bite block, which, when remembered, offers slight relief for my neck. Strength-wise, I’ve been increasing my weights at the gym, except for the shoulder press due to my muscle's stagnation despite effort. The pain often radiates down to my bicep area. To relieve tension each morning, I hold my arms above my head, stretching out my shoulders; however, this often results in heat and increased numbness after lowering my arms. I frequently roll my shoulders and arch my back throughout the day to stretch out the discomfort. I’ve recently been experiencing an odd ‘pinch’ sensation in my brain periodically, which dissipates when I maintain an upright posture. Slouching while driving contributes to fatigue, but correcting my posture alleviates this feeling. This discomfort can resemble dizziness, making me feel faint, but stretching seems to provide temporary relief. Additionally, I have been dealing with episodes of intense tinnitus, characterized by both ringing and a disturbing vibration that renders me unable to hear anything during these phases. I am considering purchasing a new pillow specifically designed for cervical spine support, suspecting that I might have compressed discs in my neck. I appreciate any insights or advice on this matter. Due to my job, responses to comments may be delayed, but I am grateful for your attention!
Understanding MRI Findings for Neck Discomfort
A 26-year-old female who is not currently on any medications seeks clarification regarding her MRI results. Although her neurologist has yet to analyze the findings, she underwent a cervical MRI due to enduring neck and back pain, along with some weak sensation in her right arm. She also experiences occasional stiffness in her back, primarily in the morning or when bending forward. **C2/C3**: There are no significant issues with spinal canal or foraminal stenosis. **C3/C4**: There is disc osteophyte formation detected, but no notable spinal canal stenosis, and the foramina are open. **C4/C5**: Presence of central disc osteophyte formation; however, no spinal canal stenosis is observed and the foramina remain open. **C5/C6**: Central disc osteophyte formation is noted. There is minimal spinal canal stenosis, but no significant narrowing of the foramina is present. **C6/C7**: Further disc osteophyte formation is observed without any spinal canal stenosis, and the foramina are clear. **C7/T1**: No evidence of spinal canal stenosis, and the foramina are unobstructed.
Reevaluating My Upcoming Colonoscopy and Endoscopy at 34
Hello everyone, I am approaching my 35th birthday this year. I weigh 145 pounds, stand 5 feet 10 inches tall, and maintain an active lifestyle. My blood tests typically show good results, although I do have slightly elevated LDL levels (124 mg/dL reported in my last test). I also have a history of anxiety, particularly concerning health issues. A few years back, I was diagnosed with H. Pylori and have been grappling with SIBO for the last 2-3 years. I completed a course of antibiotics for H. Pylori but have refrained from using antibiotics for SIBO. I've encountered numerous narratives suggesting that SIBO can recur, especially if the underlying cause isn’t resolved, and I’m hesitant to rely on antibiotics if they aren't a permanent solution. The SIBO symptoms I experience include constipation, bloating, a sensation of fullness that seems disproportionate to my weight, belching, and gas in my lower abdomen leading to discomfort during physical activity. An ultrasound identified cholesterol polyps; however, my gastrointestinal doctor did not find it necessary to schedule regular follow-ups. Increasing my fiber intake has generally alleviated some of my symptoms, albeit inconsistently. Over the years, my overall condition appears to have stabilized or improved slightly, which my doctor considers a reassuring sign since my symptoms are not worsening. Currently, I am taking: - Tudca to facilitate movement - Sunfiber - A rotating regimen of S. Boulardii and Akkermansia - Various other supplements not aimed at digestion (taken intermittently), such as vitamin D, chlorella, zinc, Cialis, ashwagandha, boron, and lithium orotate. I have not been using antimicrobials recently but have tried biofilm disruptors paired with berberine for several weeks multiple times. There is no known family history of colon or gastric cancer, but due to my digestive challenges and the increasing incidence of colorectal cancer among younger adults, I deemed it wise to proceed with a colonoscopy and endoscopy. The plan is to include a small biopsy during the endoscopy. I also began experimenting with peptides like BPC-157 and TB-500 for injury recovery, but I've come across concerns regarding the potential risk of encouraging the growth of existing cancers within the body, which has made me reconsider. Several individuals I have spoken with suggest that I am too young for these procedures and express concerns about associated risks. I welcome any professional insights on this matter. Lastly, the doctor I have chosen for these procedures is highly rated and appears knowledgeable, yet none of the reviews address surgical experience. What qualifications or questions should I be considering in selecting a physician if I proceed with the procedures?
Ultrasound Analysis
My 88-year-old grandmother underwent an abdominal and pelvic ultrasound. Following this procedure, her doctor arranged a consultation due to certain concerning discoveries pertaining to her liver. The ultrasound results indicated a slight degree of fat accumulation in the liver, which remained of standard size. However, there were two unspecified hypoechoic masses reported (measuring 3.7 x 3.6 x 2.7 cm and 1.9 x 1.5 x 1.9 cm), prompting the need to exclude the possibility of malignancy. The doctor recommended a multiphase abdominal CT for more detailed assessment. Overall, the description of these masses felt rather ambiguous, as no further details regarding her liver were provided. Fortunately, her blood results appeared normal, and no other issues were identified during the ultrasound. This situation has left us feeling highly anxious about what these findings could imply. To give you some context, she was diagnosed with breast cancer in 2021 and currently continues her treatment with mar-letrozole. Interestingly, though the ultrasound report was marked as "urgent," the appointment for her multiphase CT scan is scheduled for March 26, which feels quite distant. We hope to secure an earlier slot at a local hospital for the CT scan. I would greatly appreciate any insights or advice regarding the ultrasound results. Should we be particularly alarmed about the potential for a recurrence?
Experiencing Unusual Bleeding
As a 19-year-old female currently taking the mini pill for several months, I've just noticed some unexpected bleeding. Until now, I hadn't experienced any bleeding, but this episode comes with discomfort as well. Recently, I've also been dealing with lower abdominal pain, and there was a possibility of a urinary tract infection, for which I just completed a course of antibiotics. Given these recent developments, is this something I should worry about?
