How Sleep Affects Your Dental Health

The Sleep-Oral Health Connection

Quality sleep is essential for overall health, including your mouth. At FB Dental Yarrabilba, we recognise the bidirectional relationship between sleep and oral health—each significantly affects the other.

Sleep Bruxism

Many people grind or clench teeth during sleep without realising it. Symptoms include morning jaw pain, headaches, worn tooth surfaces, and cracked teeth. Partners may hear grinding sounds. A custom night guard protects teeth while you sleep.

Sleep Apnoea and Oral Health

Obstructive sleep apnoea causes breathing interruptions during sleep. Symptoms include loud snoring, daytime fatigue, and morning dry mouth. Sleep apnoea is linked to teeth grinding, gum disease, and tooth decay. Dentists often notice signs of sleep apnoea during examinations and can refer for specialist assessment.

Dry Mouth During Sleep

Mouth breathing during sleep causes significant dry mouth. Without saliva's protective effects, bacteria thrive, increasing cavity and gum disease risk. You may notice bad morning breath, cracked lips, and increased thirst upon waking.

Sleep and Immune Function

Poor sleep weakens immune response, reducing your body's ability to fight oral infections. Gum disease may progress faster in those who are sleep-deprived. Healing after dental procedures can also be compromised.

Protecting Your Oral Health

Maintain consistent sleep schedules. Address snoring or suspected sleep apnoea with medical consultation. Brush before bed—never sleep with food particles on teeth. Stay hydrated but avoid sugary drinks before sleep.
