Save the tooth : Power of Root Canal
🦷 What is Pulpitis?
Pulpitis is inflammation of the dental pulp — the innermost part of the tooth that contains nerves and blood vessels. It causes pain and sensitivity, and can lead to more serious infections if untreated.
🦠 What Happens If Untreated?
The pulp dies → leads to necrosis.
Infection can spread to the root tip → periapical abscess.
This may cause swelling, pus, or even systemic infection.
🛠️ Treatment Options:
Reversible pulpitis: Remove decay, place a filling/ restoration.
Irreversible pulpitis: Root canal treatment or tooth extraction.
⚠️ How Decay Progresses to Pulpitis:
Tooth decay doesn’t cause pulpitis immediately — it progresses through several layers of the tooth:
1. Enamel Stage (Early Decay)
Decay begins when bacteria in plaque produce acid that dissolves the enamel, the tooth’s hard outer layer.
At this stage, there's no pain. You might see white spots or brown discoloration.
2. Dentin Stage (Advanced Decay)
Once decay penetrates the enamel, it reaches the dentin, which is softer and has tiny tubules that lead to the pulp.
This causes sensitivity to cold, sweet, or acidic foods.
3. Pulp Involvement ➡️ Pulpitis
If decay continues, it reaches the pulp chamber, infecting the soft tissue inside.
The body responds with inflammation, leading to:
- Reversible pulpitis: mild pain, pulp can recover if treated early.
- Irreversible pulpitis: severe, lingering pain; pulp cannot heal and will eventually die.
🔥 Symptoms of Pulpitis:
Sharp or throbbing toothache
Pain that worsens at night or with cold/hot stimulus
Sensitivity to pressure or chewing
Swelling (in more advanced cases)
牙痛一定要拔牙吗？根管治疗 ，给你的牙齿多一次机会
🦠 如果不治疗，会发生什么？
牙髓坏死 → 导致组织坏死
感染扩散至牙根尖 → 形成根尖脓肿
可能出现肿胀、化脓，甚至引发全身感染
🛠️ 治疗选择：
可逆性牙髓炎： 清除龋坏，补牙或进行牙齿修复
不可逆性牙髓炎： 根管治疗或拔牙
🦷 什么是牙髓炎？
牙髓炎是牙髓（牙齿最内部，含有神经和血管的组织）的炎症。它会引起疼痛和敏感，如果不治疗，可能导致更严重的感染。
⚠️ 蛀牙如何发展成牙髓炎：
蛀牙不会立刻引起牙髓炎，而是逐层穿透牙齿结构
牙釉质阶段（早期蛀牙）
当牙菌斑中的细菌产生酸性物质溶解牙釉质（牙齿坚硬的外层）时，蛀牙开始了。这个阶段通常无痛，可能会看到白斑或棕色变色。
牙本质阶段（进展性蛀牙）
当蛀牙穿透牙釉质后，就会到达牙本质，这一层较软，并含有通往牙髓的小管。这会引起对冷的、甜的或酸性食物的敏感。
牙髓受累 ➡️ 牙髓炎
若蛀牙继续发展，会侵入牙髓腔，感染内部的软组织。身体对此作出炎症反应，导致：
- 可逆性牙髓炎： 轻微疼痛，若及早治疗可恢复；
- 不可逆性牙髓炎： 剧烈、持续性疼痛，牙髓无法自愈，最终会坏死。
🔥 牙髓炎的症状：
尖锐或跳动性的牙痛
夜间或冷热刺激时疼痛加剧
对咬合或咀嚼的敏感
（严重时）出现肿胀
