🦷 What is Intermittent Fasting?
Impact of Intermittent Fasting on Oral Health Intermittent fasting involves cycling between periods of eating and fasting. Common methods include:
- 16:8: 16 hours of fasting and an 8-hour eating window
- 5:2: Normal eating for 5 days, very low calorie intake on 2 non-consecutive days
- OMAD: One Meal A Day
Impact of Intermittent Fasting on Oral Health While the health benefits are widely discussed, few consider the oral health implications.
🔍 How Intermittent Fasting Affects Your Oral Health
1. Dry Mouth (Xerostomia)
Fasting often reduces water intake and saliva production, leading to dry mouth. This can:
- Increase the risk of cavities
- Promote bacterial growth
- Cause bad breath
Impact of Intermittent Fasting on Oral Health Our Smile Specialists in Chennai often point out that saliva is your mouth’s natural defense. During fasting, when saliva production drops, bacteria have more opportunity to grow.
2. Bad Breath (Halitosis)
Impact of Intermittent Fasting on Oral Health a common complaint during fasting is bad breath. Without regular eating, the body produces ketones, which release a foul-smelling chemical called acetone.
Impact of Intermittent Fasting on Oral Health We regularly advise patients at Dr.D’s Dentistry, especially those looking for a Smile Designer in Chennai, to stay hydrated and maintain oral hygiene during fasting hours.
3. Enamel Erosion Risk Post-Fast
Impact of Intermittent Fasting on Oral Health Breaking a fast with acidic or sugary foods, like fruit juices, citrus fruits, or sweets, can damage enamel, especially if you brush immediately after.
Our Root Canal Specialists in Chennai caution against brushing teeth directly after acidic meals. Instead, rinse with water and wait at least 30 minutes.
