Chihuahua Teeth Problems: Common Issues and Essential Care Guide

Why Chihuahuas Have the Worst Dental Problems

Chihuahuas are notorious for dental issues. In fact, they're considered one of the breeds most prone to dental disease. By age 2, most Chihuahuas already show signs of dental problems.

The perfect storm of risk factors:

• Tiny jaws packed with 42 teeth
• Severe tooth crowding
• Weak enamel in some lines
• Long lifespan (12-20 years)
• Often picky eaters (less natural cleaning)
• Genetic predisposition

Most Common Chihuahua Dental Problems

1. Extreme Tooth Crowding

The #1 issue. A Chihuahua's mouth is barely bigger than a human thumb, yet contains the same number of teeth as a Labrador.

What happens:

• Teeth overlap and twist
• Food traps between teeth
• Impossible to clean all surfaces
• Bacteria thrive in hidden pockets
• Rapid plaque buildup

Most affected areas:

• Front teeth (incisors often overlap)
• Lower jaw premolars
• Teeth behind canines

2. Retained Baby Teeth

Extremely common in Chihuahuas—up to 50% have retained baby teeth.

Problems caused:

• Double teeth in same spot
• Adult teeth grow crooked
• Food and bacteria trapped
• Bite misalignment
• Accelerated decay

When to act:

• Check at 6-7 months
• If any baby teeth remain after adult teeth erupt
• Extraction usually recommended
• Earlier is better

3. Periodontal Disease

Progresses faster in Chihuahuas than larger breeds.

Timeline in Chihuahuas:

• Age 1-2: Gingivitis often present
• Age 2-4: Periodontitis may begin
• Age 5+: Significant bone loss common
• Age 8+: Tooth loss without treatment

Signs:

• Red, swollen gums
• Extremely bad breath
• Yellow-brown buildup
• Loose teeth
• Pain while eating
• Blood on toys or in water

4. Tooth Loss

Many Chihuahuas lose teeth earlier than other breeds.

Causes:

• Untreated periodontal disease
• Bone loss around roots
• Tooth root abscesses
• Trauma (fragile teeth)

Impact:

• Difficulty eating
• Tongue may hang out
• Changed facial appearance
• Need for soft food diet

5. Tooth Root Abscesses

Common complication of dental disease in Chihuahuas.

Signs:

• Swelling under eye or on jaw
• One-sided facial swelling
• Refusing to eat
• Fever
• Rubbing face on ground

Urgency: Veterinary emergency—see vet same day.

6. Jaw Fractures

Chihuahuas' weakened jaw bones from dental disease can actually fracture.

Risk factors:

• Severe periodontal disease
• Bone loss around teeth
• Trauma (even minor)
• Dental procedures on diseased jaws

Prevention: Regular dental care prevents the bone loss that leads to fragile jaws.

The Chihuahua Dental Care Plan

Daily Care (Non-Negotiable)

For Chihuahuas, daily dental care isn't optional—it's essential.

Brushing:

• Frequency: Daily, ideally
• Minimum: Every other day
• Tool: Extra-small or finger brush
• Paste: Pet enzymatic toothpaste
• Duration: 1-2 minutes

Technique for tiny mouths:

1. Use finger brush or baby toothbrush
2. Focus on outer surfaces only
3. Angle brush to reach gumline
4. Very gentle pressure
5. Work in sections
6. Reward immediately

Dental Chews for Chihuahuas

Choose carefully—wrong size can choke or break teeth.

Safe options:

• Extra-small, VOHC-approved
• Soft enough to flex
• Dissolve if swallowed
• Avoid anything you can't dent with thumbnail

Products to avoid:

• Any "bone" products
• Antlers (too hard)
• Standard-size chews
• Hard nylon toys

Water Additives

Easy supplement for tiny dogs:

• Add to fresh water daily
• Look for VOHC approval
• Safe and unflavored options best
• Not a replacement for brushing

Professional Care Schedule

Chihuahuas need more frequent professional care than most dogs.

Reality: Many Chihuahuas need professional cleanings 1-2 times per year their entire lives.

Signs Your Chihuahua Needs Immediate Vet Care

Emergency (Same Day)

• Facial swelling (tooth abscess)
• Unable or unwilling to eat at all
• Bleeding from mouth
• Extreme pain (crying, hiding)
• Loose jaw or clicking sound

Urgent (Within 1-2 Days)

• Refusing hard food
• Dropping food while eating
• Pawing at mouth
• Very bad breath suddenly
• Visible loose tooth

Schedule Soon (1-2 Weeks)

• Gradual breath worsening
• Visible tartar buildup
• Red gums
• Chewing on one side
• Due for regular cleaning

Cost Reality for Chihuahua Owners

Budget for dental care—it's one of the biggest ongoing costs for Chihuahua ownership.

Typical costs:

Long-term view:

• Prevention is MUCH cheaper than treatment
• A $10 toothbrush saves thousands
• Pet dental insurance may be worthwhile
• Ask about wellness plans

Living with a Chihuahua Who's Lost Teeth

Many Chihuahuas eventually lose some or many teeth. Here's what to expect:

Eating adjustments:

• Soft food works great
• Most adapt quickly
• Some can still eat kibble
• Tongue may stick out (harmless)

Quality of life:

• Often improves after extractions
• Pain-free eating
• Better breath
• More energy

Don't delay extractions out of worry—painful teeth are worse than no teeth.

Chihuahua Dental Myths

Myth: "Small dogs don't need dental care"

Truth: Small dogs need MORE dental care due to crowding.

Myth: "Bad breath is normal for Chihuahuas"

Truth: Bad breath indicates disease—it's not breed-normal.

Myth: "Dental cleanings are too risky for tiny dogs"

Truth: Modern anesthesia is safe; untreated dental disease is riskier.

Myth: "My Chihuahua won't let me brush"

Truth: With patience and training, most accept it eventually.

Myth: "Dry food cleans teeth"

Truth: Provides minimal cleaning; brushing is essential.

Tips for Reluctant Chihuahuas

Many Chihuahuas resist dental care. Try:

For brushing resistance:

1. Start with just tasting toothpaste
2. Touch teeth without brushing (week 1)
3. Brief brushing (week 2)
4. Build to full routine (week 3-4)
5. Use high-value rewards
6. Keep sessions short and positive

If brushing truly isn't possible:

• Dental wipes (easier than brushes)
• Dental gels applied to gums
• Water additives
• More frequent professional cleanings

Something is always better than nothing.
