It usually happens in a kitchen, a workshop, or a yard: a slip, a sharp edge, and suddenly you are pressing a towel to a cut and trying to work out whether this needs stitches or just a bandage and time. Here is a simple way to judge it, the first aid to do while you decide, and the one factor most people do not know about: the clock.
Signs a cut probably needs stitches
- It is deep. You can see yellow fat tissue, or deeper structures such as muscle or tendon, instead of just skin.
- It gapes open. The edges pull apart and do not stay together on their own, especially when the skin moves.
- It is long. As a rough guide, cuts longer than about half an inch on the body, or a quarter inch on the face, usually need closing.
- It will not stop bleeding. Steady bleeding that continues after 10 to 15 minutes of firm, direct pressure.
- It is on a joint or a high movement area. Cuts over knuckles, knees, and elbows reopen every time you move, and heal poorly without help.
- It is on the face. Facial cuts are closed carefully and early, both for healing and for the scar.
- It was caused by a bite. Human and animal bites carry a high infection risk and need assessment even when they look small.
Cuts that are shallow, stop bleeding on their own, and whose edges sit together neatly usually heal fine with cleaning, antibiotic ointment, and a bandage. When in doubt, having it looked at the same day is always the safer call.
First aid while you decide
- Apply pressure. Use a clean cloth or gauze and press firmly and steadily. Peeking every minute restarts the process, so hold for a full 10 to 15 minutes.
- Elevate. Raise the injured area above the level of your heart if you can. It genuinely slows bleeding.
- Rinse. Once bleeding is controlled, run the cut under clean water to wash out dirt and debris. Skip the hydrogen peroxide and scrubbing, which damage tissue.
- Cover. A clean bandage or dressing while you travel keeps the wound protected.
The clock: why same day matters
Stitches work best when they are placed early, ideally within about 6 to 8 hours of the injury. The longer a cut stays open, the more bacteria settle in, and past a certain point, commonly around 24 hours, closing it traps infection inside and does more harm than good. Providers can sometimes still close older wounds on the face, where blood supply is excellent, and there are delayed closure options for other wounds. But an old cut often has to heal open instead, which is slower and leaves a worse scar. If a cut might need stitches, the time to decide is now, not tomorrow.
Cuts that belong in the ER, not urgent care
- Bleeding that spurts, or that soaks through dressings and will not stop with pressure
- A deep cut on the hand with any loss of movement or feeling in a finger
- Anything embedded in the wound, such as glass or metal, that you cannot gently wash out. Leave it in place and let a provider remove it
- A cut with a possible broken bone underneath, or a wound from a crush injury
- Bites to the face or hands, or any bite that is already red, swollen, and painful

The tetanus question
Cuts are when tetanus comes up, especially cuts from dirty, rusty, or soil contaminated objects. You need a tetanus booster if your last one was more than 10 years ago, or more than 5 years ago for a dirty wound. If you were never vaccinated or do not know your status, tell the provider, because the plan is different. Bringing it up is part of the visit whether you raise it or not, so do not be surprised when we ask.
Not always stitches: strips and glue
Some cuts that need closing do not need thread. Shallow cuts with straight edges that meet easily can be closed with adhesive strips or medical skin glue, which is quicker and, for children, much less frightening. The provider chooses based on depth, location, and tension on the skin. Stitches remain the strongest option for deep cuts and cuts over joints.
Aftercare and infection warning signs
Keep the wound clean and dry for the first 24 to 48 hours, then follow the care instructions you are given. Stitches are usually removed in 5 to 14 days depending on location, and we will tell you your date before you leave. Watch for infection: spreading redness, increasing pain after the first day or two, swelling, warmth, red streaks running from the wound, pus, or a fever. Any of those means come back promptly, do not wait for the removal appointment. You can book a visit online or walk in.
Frequently asked questions
How deep is too deep?
If you can see fat, which looks yellow and lumpy, or anything deeper, the cut needs closing. The other practical test is gaping: if the edges will not stay together, it will not heal well on its own, whatever its measured depth.
How long do I have to get stitches?
Ideally within 6 to 8 hours. After roughly 24 hours, most cuts can no longer be closed safely in the usual way. If you are reading this with an older cut, still come in: the wound needs proper cleaning and assessment even if it ends up healing open.
Will it scar?
Any cut deep enough to consider stitches will leave some mark, but a cut that is cleaned and closed early, with edges lined up neatly, heals with a much finer scar than one left to close on its own. Face cuts are the clearest example of why early, careful closing matters.
Do I need a tetanus shot?
If your last booster was over 10 years ago, or over 5 years ago and the wound is dirty, yes. If you are unsure of your vaccination history, tell us and we will sort it out during the visit.
Can urgent care do this, or do I need the ER?
Urgent care handles the large majority of cuts that need stitches, including cleaning, numbing, closing, and tetanus boosters. The ER list is short: uncontrolled bleeding, embedded objects, deep hand injuries with movement or feeling loss, and wounds over fractures.
