If you have a toothache, you may be aware of it as you go about your daily activities. However, it might not stop you from accomplishing what you need to. When you lie down to sleep at night, though, things may be different. Perhaps the pain gets a lot worse — it may even prevent you from getting the rest you need! Why do toothaches often seem to worsen at night, and what can you do to finally get some sleep? This blog post provides helpful advice.

Increased Blood Flow

One major reason toothaches often feel worse at night is increased blood flow to your head when you lie down. During the day, gravity helps keep blood from pooling in your mouth and head. But at night, as you recline, more blood naturally flows to these areas. This extra circulation can put additional pressure on your tooth nerves, intensifying any pain or discomfort you might already be feeling.

Late Night Snacks & Meals

If you indulge in late night snacks or meals, you could unknowingly be making your toothache worse. Eating sugary or acidic foods, or even just eating close to bedtime, gives bacteria in your mouth more fuel to create acids that irritate sensitive teeth and gums. Food particles left behind can also get trapped in cavities or between teeth, making existing pain more noticeable when you settle in to sleep.

Unconscious Teeth Grinding

Many people clench or grind their teeth while sleeping — a condition known as bruxism. You might not even know you do this, but it can put a lot of strain on your teeth and jaw. If you already have a sensitive tooth, grinding during the night can make the pain much worse and even lead to headaches or jaw soreness when you wake up. Over time, this habit can wear down tooth enamel and contribute to further oral health issues.

Fewer Distractions

During the day, you are often busy at work, running errands, or spending time with friends and family. All these activities serve as distractions from minor aches and pains. At night, however, things tend to quiet down, and you are left alone with your thoughts — and your toothache. Without anything else to focus on, the pain can seem more intense, making it harder to fall asleep or stay asleep.

Tips for Sleeping with a Toothache

These tips might help you finally get some rest:

  • Prop your head up with extra pillows to help reduce blood flow to your mouth and ease pressure on your tooth.
  • Apply a cold compress to your cheek for 15 – 20 minutes to numb the area and help reduce swelling.
  • Avoid eating sugary, acidic, or hard foods before bedtime, and brush and floss thoroughly to keep your mouth clean.
  • Try rinsing your mouth with warm salt water to help reduce inflammation and kill bacteria.
  • Take over-the-counter pain relievers as directed to relieve discomfort.
  • If you suspect you grind your teeth, ask your dentist about getting a mouthguard to protect your teeth while you sleep.

While these tips can help you get through the night, remember that ongoing tooth pain is a sign you should schedule a dental appointment as soon as possible! Addressing the underlying cause is the best way to get relief and protect your oral health.
