Yes, you can make your tongue stronger. The tongue is made of eight muscles, and like other muscles in your body, they respond to targeted resistance training. Healthy adults typically generate about 62 kilopascals of tongue pressure in young and middle age, declining to around 51 kPa after age 60. With consistent exercises, measurable strength gains show up in as little as four weeks.
How Tongue Strength Works
Your tongue contains four intrinsic muscles that change its shape (curling, flattening, narrowing) and four extrinsic muscles that move it around inside your mouth. When you press your tongue against the roof of your mouth, you’re using both groups together. Tongue strength builds a little differently than bicep or quad strength, though. Research on tongue exercise found that despite clear increases in the force the tongue could produce, individual muscle fibers didn’t get significantly larger. In a typical skeletal muscle, fiber hypertrophy (the fibers literally getting thicker) is the main way you get stronger. The tongue seems to rely more on improved neural coordination and recruitment of existing muscle fibers, at least in the short term. Longer training periods may eventually produce fiber growth, but the early gains come from your brain getting better at activating the muscles you already have.
Exercises That Build Tongue Strength
Most tongue-strengthening routines use the same principle: press the tongue against resistance and hold. Here are the most common approaches.
- Tongue press (push-ups): Press the tip of your tongue firmly against the roof of your mouth, or push upward against a spoon or popsicle stick. Hold for a few seconds, then release. Repeat 10 times per set.
- Tongue pull: Gently extend your tongue outside your mouth and hold it with light finger pressure while resisting in different directions: left, right, up, and down. This targets the extrinsic muscles that control tongue positioning.
- Tongue circles: Trace your tongue around the outside of your teeth in small circles, four to five laps in each direction. Work up to 15 circles per direction, three times a day.
A clinical protocol used with stroke patients prescribed 5 sets of 10 repetitions per day (50 total presses), targeting both the front and back of the tongue, performed 5 days a week for 6 weeks. That’s a reasonable framework if you want a structured routine, though healthy adults doing less intensive programs still see results.
How Long Until You See Results
A study on older adults found that four weeks of self-administered tongue exercises produced measurable improvements in both tongue strength and endurance. In sleep apnea patients, just one week of daily tongue-task training was enough to reduce breathing disturbances during sleep by 23% overall. The tongue responds relatively quickly to training compared to larger muscle groups, partly because those early gains depend on neural adaptation rather than building new tissue. For sustained improvement, plan on at least four to six weeks of consistent practice.
Why Tongue Strength Matters
Swallowing
A weak tongue leaves food residue in the mouth and throat, lengthens meal times, and in more serious cases raises the risk of food or liquid entering the airway. Tongue-strengthening exercises have been shown to increase maximum tongue pressure, reduce residue in the throat after swallowing, and decrease aspiration risk. This is particularly relevant for older adults and people recovering from stroke or neurological conditions, but even healthy people lose tongue strength with age.
Sleep Apnea
When tongue muscles are weak, the tongue is more likely to collapse backward during sleep and block the airway. In a pilot study of 10 patients with moderate sleep apnea, one week of tongue training reduced nighttime breathing interruptions from about 21 events per hour to 16. During the deepest phase of sleep (REM), when muscles are most relaxed and the airway is most vulnerable, interruptions dropped by 48%. Forty percent of patients improved from moderate to mild severity. Tongue exercises won’t replace a CPAP machine, but they can be a useful addition to treatment.
Speech Clarity
Maximum tongue strength correlates with the speed of tongue movement during speech. People with neurological conditions affecting speech showed significantly lower tongue pressure, speech clarity, and articulation speed compared to healthy speakers. The relationship is specifically tied to how quickly the tongue can shift positions while forming sounds. Stronger tongue muscles can move faster between positions, which makes speech crisper and more intelligible.
Tracking Your Progress
Clinicians measure tongue strength using a device called the Iowa Oral Performance Instrument (IOPI), a small handheld tool with an air-filled bulb you press against the roof of your mouth. It reads pressure in kilopascals. Normal adult tongue strength ranges from 43 to 78 kPa, with the average around 62 kPa for young and middle-aged adults. Children start around 21 kPa at age 3 and reach adult-level values by their mid-teens.
If you don’t have access to clinical equipment, you can track progress informally. Notice whether you can hold a tongue press against resistance for longer, whether you can complete more repetitions before fatigue, or whether swallowing and speech feel easier. Some speech-language pathologists offer tongue strength assessments if you want a baseline number.
Practical Tips for a Training Routine
Start with 3 sets of 10 tongue presses per day, pushing firmly against the roof of your mouth. Add tongue circles and directional resistance work as the basic press gets easier. Five days a week is sufficient. You don’t need equipment to start, though a spoon provides a simple external resistance target that helps you push harder and more consistently than pressing against your own palate alone.
Tongue fatigue during training is normal and actually a sign you’re working the muscles adequately. If you notice jaw soreness or pain that persists after a session, scale back your repetitions and check that you aren’t clenching your jaw while doing the exercises. The effort should come from the tongue itself, not from the surrounding muscles. Most people find that building tongue exercises into an existing habit, like doing them right after brushing your teeth, makes consistency easier to maintain.
