Why is the gum irritated around one tooth?
Gum irritation around one tooth often reflects plaque, trapped food, a sharp edge, decay, or a problem affecting that tooth.
What can irritate the gum collar around a tooth?
The gum collar around a tooth can become tender when plaque or food presses into the sulcus. A cavity, crack, rough filling, erupting wisdom tooth, or foreign body can produce the same pattern.
How can I clean around the irritated gum?
Rinse, brush gently, and clean between the teeth with floss or an interdental brush without forcing it. Do not poke or scrape the gum.
When does irritation around a tooth need care?
Arrange examination if it lasts, recurs, or comes with toothache, bleeding, pus, bad taste, swelling, or pain on biting.
Could decay or a crack be irritating this gum?
Ask whether the tooth has decay, a crack, a defective filling, or a deep pocket, and whether an x-ray or cleaning is needed.
Frequently asked questions
Should I use a toothpick?
Avoid sharp objects because they can injure the papilla or push material deeper.
Why is one gum site sore?
Plaque, trapped food, decay, a crack, or a rough restoration can affect one site.
