A cracked tooth is always going to occur at an inconvenient time. Maybe you’re dealing with a result of chewing on something hard, falling down, or even having an old filling fail on you. But what everyone wants to know after a crack occurs is how much time they have until they really need to worry.
And the truth is…not much.
Once a tooth cracks, it leaves your mouth exposed to potential bacterial infections far sooner than you may think—sometimes even within hours of the crack happening.
At Cunning Dental in Montclair, CA, it is not uncommon for us to see patients who thought a few days wouldn’t hurt, only for them to find out how wrong they were.
What Happens When a Tooth Breaks?
The tooth is not only made up of one structure but several different layers:
- The enamel (tough layer covering the tooth)
- The dentine (sensitive layer underneath the enamel)
- The pulp (the inner layer consisting of nerves and blood supply)
If the tooth cracks, particularly past its outer protective layer, then the dentine or even the pulp becomes exposed to external influences.
This is like breaking the seal on the container. Bacteria are now free to enter. Now think about your mouth for a moment; it is teeming with bacteria, upwards of hundreds of different species, regardless of your oral hygiene practices.
The probability of infection is greatly increased once bacteria enter the pulp chamber.
How Fast Can Infection Develop?
But here’s where it gets complicated because there is no universal answer to that question.
On the one hand, in some situations:
- The infection process starts after several hours of exposure.
- A minor fracture manifests itself after several days.
So, why the difference?
Because it all depends on:
- The depth of the fracture
- Whether the pulp is damaged
- Hygiene levels in the affected area
- The reaction of your immune system
A small flake is like a cut; it won’t pose any problems immediately. However, a deep crack with the nerve exposed will be closer to an injury.
And injuries always become infected sooner rather than later.
Signs of Infection to Watch For
Infection can be subtle sometimes, whereas it can also be quite overt other times.
- Pain that is constant or pulsating
- Swollen tooth or jaw
- Pain from hot or cold food that persists
- An unpleasant taste in your mouth
- Presence of pus or discharge in the area surrounding the tooth
- Fever (more advanced cases)
One important point to keep in mind:
Not all infections hurt, and not everyone who doesn’t have pain is healthy.
We have encountered patients who did not experience much pain but had an infection beneath the surface.
Factors That Increase Infection Risk
Broken teeth do not always get infected equally quickly. Some factors make infection occur more rapidly.
1. Depth of Tooth Fracture
A small crack is less likely to lead to infection than a deep one reaching the pulp.
2. Dental Hygiene
When there are more bacteria present in the mouth, infection can occur more rapidly.
3. State of Your Immune System
If your immunity is lowered because of certain diseases, stress, or even diabetes, you might be more prone to infections.
4. Time Spent Without Medical Help
Time plays an important role here.
Immediate Steps to Take
Don’t get scared, but you definitely shouldn’t leave it untreated either.
1. Rinsing Your Mouth
Do it with warm salt water.
2. Covering Sharp Teeth Edges
If the affected tooth has sharp edges, cover them with dental wax or sugarless chewing gum for the time being.
3. Not Putting Pressure on the Affected Area
Don’t chew anything from that side.
4. Taking Care of Pain
OTC painkillers can help, but never put aspirin directly on your teeth.
5. Calling a Dentist
No matter how small the problem is, do it as soon as possible.
That is by far the most crucial thing to do.
Treatment Options
It relies on how flawed the crack is.
Dental Bonding
In cases of minor cracks, dental bonding can reshape the tooth easily.
Dental Crowns
In cases where there is extensive damage to the teeth, crowns protect the affected area.
Root Canal Treatment
If there is an infection inside the tooth, a root canal cleans out the infection and prevents further complications.
All of these procedures are commonplace, but timing is essential. One day’s delay could transform a straightforward bonding procedure into a complex root canal treatment.
What Happens If You Delay Treatment?
Here’s where the problem may begin to intensify.
An infected tooth will spread the infection beyond itself.
Potential complications involve the following:
- An abscess (or accumulation of pus)
- Intense pain and swelling
- Spread of the infection to the nearby tissues.
- Loss of bone mass surrounding the tooth
- Loss of the tooth
In some extremely rare cases, the infection that started from the teeth can cause other problems in the body.
Again, it’s not meant to frighten anyone.
Prevention Tips
Though accidents cannot always be prevented, there are ways to decrease the chances of a tooth fracture occurring.
- Wear a mouth guard while engaging in any sports activity.
- Refrain from eating hard objects like ice.
- Refrain from using your teeth to open bottle caps (something we’ve all done before)
- Visit your dentist regularly.
Most of the cases of tooth fracture we encounter do not happen instantly; they happen to weakened teeth.
When to Seek Emergency Care
There are some cases that can’t wait for even a single day.
In case you have any of these symptoms, seek dental treatment immediately:
- Intense pain
- Facial or jaw swelling
- Any signs of an abscess (pimple-like bumps on the gums)
- Fever or trouble swallowing.
This implies the infection is already spreading.
Conclusion
Then, how fast does an infection develop in a cracked tooth?
Surprisingly quick!
Within just hours or perhaps a couple of days. Once bacteria manage to get into your tooth, however, they will start working.
One thing is sure, though:
Don’t wait for the pain to make sure that something isn’t right.
If your tooth is broken, fractured, or chipped, you’ll do yourself a favor by coming to us sooner rather than later.
