Oral surgery often requires stitches to close wounds and promote healing. Unlike traditional stitches that require removal by a healthcare professional, some stitches used in the mouth are designed to dissolve on their own. This process is a fascinating example of biocompatible materials interacting with the body's natural healing mechanisms. But how exactly do these stitches dissolve?
What Are Dissolving Stitches Made Of?
Dissolving stitches, also known as absorbable sutures, are made from materials that the body can naturally break down. The most common materials are:
-
Polyglycolic acid (PGA): This synthetic polymer is a popular choice for absorbable sutures due to its strength and predictable absorption rate. The body's enzymes gradually break down the PGA molecules into lactic acid and glycolic acid, which are then absorbed into the bloodstream and processed by the liver.
-
Polylactic acid (PLA): Similar to PGA, PLA is a synthetic polymer that's broken down by hydrolysis—a chemical reaction with water. This process gradually weakens the suture until it completely dissolves.
-
Polydioxanone (PDO): This material offers longer-lasting strength than PGA or PLA, making it suitable for situations requiring more prolonged support during healing. It also undergoes hydrolysis, breaking down slowly over time.
How Long Does it Take for Dissolving Stitches to Dissolve?
The time it takes for dissolving stitches to disappear completely varies depending on the material used and the location within the mouth. Generally:
- PGA and PLA stitches: These often dissolve within a few weeks.
- PDO stitches: These can take several months to fully dissolve.
Your oral surgeon will advise you on the type of suture used and the expected timeframe for complete absorption. It's crucial to follow their instructions regarding post-operative care to ensure proper healing.
What Happens During the Dissolving Process?
The process is gradual and typically painless. As the body breaks down the suture material, it weakens and eventually fragments. These small fragments are then absorbed into the body's system, leaving no trace. You might notice some slight swelling or a little discomfort as the body works to dissolve the stitches, but this usually subsides quickly.
Will I Feel the Stitches Dissolving?
No, you shouldn't feel the stitches dissolving. The process is a gradual chemical breakdown, not a physical pulling or tearing sensation. If you experience significant pain or discomfort, it's important to contact your oral surgeon.
What if My Dissolving Stitches Don't Dissolve?
While rare, there's a possibility that the stitches might not dissolve completely. This could be due to various factors, including infection or an individual's unique metabolic response. If you're concerned about the stitches not dissolving as expected, it’s essential to consult your dentist or oral surgeon. They can assess the situation and determine the best course of action, which may involve surgical removal.
What is the Post-Op Care for Dissolving Stitches in the Mouth?
Following your surgeon's post-operative instructions is critical for successful healing. This usually involves:
- Gentle rinsing: Rinse your mouth gently with saltwater several times a day to keep the area clean and prevent infection.
- Soft food diet: Avoid hard or crunchy foods that could dislodge or irritate the stitches.
- Avoiding smoking and alcohol: These can interfere with healing and increase the risk of infection.
- Regular check-ups: Attend all scheduled follow-up appointments with your oral surgeon.
By understanding the process of how dissolving stitches work and following proper aftercare, you can contribute to a smooth recovery after oral surgery. Remember, always consult your oral surgeon for any concerns or questions regarding your specific case. They can provide personalized guidance based on your individual needs and the type of sutures used.
